As the nation debates on whether to reopen schools this fall, President Donald Trump said schools should “100%” be open this fall, despite concerns from educator unions and others over the spread of the coronavirus.During his coronavirus news conference on Wednesday, Trump was asked whether he planned on sending his son and grandchildren back to school this fall.“Yes, I am comfortable with that,” Trump said.“I would like to see the schools open. Open 100% and we will do it safely, we will do carefully but when you look at the statistics -- I just read having to do with children and safety ---- they are very impressive. They have very strong immune systems,” Trump added.Trump said that it is his belief that children are less likely to spread the virus. But research thus far has not been conclusive to back Trump’s claims.A study released from South Korea and published by the CDC found that while children under age 9 were less likely to spread the virus, youth ages 10 through 19 were just as likely as adults of spreading the virus.The study also found that closing schools in several Chinese cities, including Wuhan, showed that school closure and social distancing significantly reduced the rate of COVID-19 among contacts of school-aged children. “The role of household transmission of SARS-CoV-2 amid reopening of schools and loosening of social distancing underscores the need for a time-sensitive epidemiologic study to guide public health policy,” the researchers wrote.The American Federation of Teachers this week pointed toward a three-point plan that the US should implement for reopening schools.“Our plan details three conditions essential for schools to reopen,” wrote Randi Weingarten, president of the American Federation of Teachers. “First, the average daily community infection rate among those tested for the coronavirus must be very low. (New York Gov. Andrew Cuomo has required the rate not to exceed 5 percent for at least 14 days.) Second, schools must employ public health protocols, including 6-feet social distancing, masks, deep cleaning and handwashing stations. Third, adequate resources must be available to enact these safeguards, including funding for additional nurses, guidance counselors and teachers to reduce class size.”Weingarten said that Trump has politicized reopening schools, and she called on Congress to approve giving schools additional funding to reopen. Weingarten projects that it would take 6 billion nationwide to provide essential services for schools."Expenses have increased because of the fight against coronavirus," she said. "They not only need funds to provide essential services, the average school will need an additional .2 million, or ,300 per student, to open its doors safely." 2770

As the nation mourns the passing of Sen. John McCain, Arizona Republicans are holding a Senate primary Tuesday in which one of the candidates suggested the announcement that McCain was stopping medical treatment was timed to hurt her campaign.Kelli Ward, a former state senator who has courted the far-right during her campaign, suggested on Facebook Saturday that McCain's family released its statement saying the senator was ending medical treatment for brain cancer was timed to hurt her chances of winning Tuesday's primary.Ward staffer Jonathan Williams posted that he wondered whether McCain's statement was released "to take media attention off" Ward's campaign, which was beginning a statewide bus tour. "I'm not saying it was on purpose but it's quite interesting," Williams wrote."I think they wanted to have a particular narrative that they hope is negative to me," Ward responded, according to a screenshot posted by the The Arizona Republic.The news broke that McCain had died hours after Ward's comment. Ward's campaign did not respond to a request for comment on the Facebook post.On Monday, less than two days after McCain died of brain cancer, Ward tweeted, "Political correctness is like a cancer!"The attacks and insensitive remarks about McCain are just the latest in a heated primary race that has seen all three candidates align themselves with President Donald Trump, who attacked McCain relentlessly for three years, rather than McCain or retiring Sen. Jeff Flake, whose seat they are seeking to fill.Their decisions show how the path McCain cut through the Trump era -- breaking with the President on foreign policy, health care, immigration and more -- complicated his relationship with diehard Republicans in a state where the GOP electorate is now demanding fealty to Trump.Ward faces Rep. Martha McSally and former Maricopa County Sheriff Joe Arpaio in Tuesday's primary for Arizona's other Senate seat. McSally is seen as the strongest general election candidate to face likely Democratic nominee, Rep. Kyrsten Sinema.McCain fended off Ward's challenge in a 2014 primary. Since then, she's made a series of insensitive comments as McCain battled brain cancer.She called on McCain to step down last year, calling him old and near "the end of life" before his diagnosis and said afterward he should resign "as quickly as possible."Ward closed the race barnstorming the state on a bus tour with right-wing media personalities Mike Cernovich and Tomi Lahren, as well as Rep. Paul Gosar."Are we going to elect another senator cut from the same cloth as Jeff Flake and John McCain?" Ward asked the crowd at a campaign event Friday, eliciting shouts of "No!"After McCain's death, Ward tweeted: "We are saddened to hear of the passing of @SenJohnMcCain. His decades of service will not be forgotten by the men & women of Arizona. May God grant the McCain family comfort and peace during this difficult time."McSally, the Republican establishment's preference in the race, has mostly remained silent on McCain during the primary.But McSally's omission of McCain's name when touting her support for the National Defense Authorization Act, which was named in McCain's honor, when McSally joined Trump at a signing ceremony at Fort Drum in New York, angered McCain's daughter Meghan McCain.McSally's "inability to even mention my father's name when discussing the bill named in his honor is disgraceful (just as it was with Trump)," Meghan McCain tweeted. "I had such higher hopes for the next generation of leadership in my home state."Throughout the campaign, McSally has sought to avoid any distance between herself and Trump.On Thursday, McSally sought to dodge last-minute controversy that could undercut her primary campaign, repeatedly avoiding reporters' questions about whether she considers Trump honest and trustworthy. The questions came after Trump attorney Michael Cohen's guilty plea and claim that Trump knew about hush payments to alleged mistresses during the 2016 campaign. McSally refused to address Trump, saying only that Cohen was "all over the map, contradicting himself, lying in order to save his ass."After McCain's passing, McSally tweeted, "John McCain was one of Arizona's greatest Senators, one of our country's finest statesmen, and an American hero who risked his life to defend this great nation. He loved this state, and he loved this country."I pray that God comforts Cindy and the entire McCain family. My heart is with them, and Arizona grieves with them."Arpaio, who was pardoned by Trump last year after being convicted of criminal contempt related to his hardline immigration tactics, complained in a since-deleted tweet on Friday that Cindy McCain had blocked him on Twitter."I tweeted out my thoughts & prayers for" McCain, his campaign account tweeted, and Cindy "BLOCKS me on twitter?"Arpaio tagged Trump and several news outlets in the tweet.The-CNN-Wire 4934

  

Authorities are investigating interference with police radio communications, websites and networks used by law enforcement and other officials during recent U.S. protests over the death of George Floyd in Minneapolis.Although the efforts to disrupt police radios and take down websites in Minnesota, Illinois and Texas aren’t considered technically difficult hacks, federal intelligence officials warned that law enforcement should be ready for such tactics as protests continue.Authorities have not yet identified anyone responsible or provided details about how the disruptions were carried out. But officials were particularly concerned by interruptions to police radio frequencies during the last weekend of May as dispatchers tried to direct responses to large protests and unrest that overshadowed peaceful demonstrations.During protests in Dallas on May 31, someone gained access to the police department’s unencrypted radio frequency and disrupted officers’ communications by playing music over their radios, according to a June 1 intelligence assessment from the U.S. Department of Homeland Security.Dallas police did not respond to questions about the incident.The assessment, which was obtained by The Associated Press, attributes the Dallas disruption to “unknown actors” and does not say how they accessed the radio frequency. It warned that attacks of various types would likely persist.“Short-term disruptive cyber activities related to protests probably will continue — various actors could be carrying out these operations — with the potential to use more impactful capabilities, like ransomware, or target higher profile networks,” the assessment warns.The assessment noted similar problems with Chicago police’s unencrypted radio frequencies during large downtown protests on May 30 followed by reports of arson, theft and vandalism. Chicago police also have not said how the radio frequencies were accessed, but an official with the city’s Office of Emergency Management and Communications told the Chicago Sun-Times that the tactic was “very dangerous.”Police around the country have encrypted their radio communications, often arguing that it’s a way to protect officers and block criminals from listening in on widely available phone apps that broadcast police radio channels. But media outlets and local hobbyists have been frustrated by the changes, which also prevent them from reporting on issues pertaining to public safety.The Department of Homeland Security issued a separate warning this week reporting that personal information of police officers nationwide is being leaked online, a practice known as “doxxing.” According to the report obtained by the AP, information shared on social media included home addresses, email addresses and phone numbers.Law enforcement agencies have been targeted by online pranksters or hackers in recent years, including by some who claimed to be motivated by on-the-ground protests against police tactics. For example, the hacking collective Anonymous claimed responsibility for the defacement of local police departments’ websites in 2012 as protesters clashed with officers during the Occupy Wall Street movement.Individuals who self-identified as being part of the collective also claimed to have accessed dispatch tapes and other Ferguson Police Department records in 2014 after a white police officer shot and killed Michael Brown, an 18-year-old black man.Like other government entities, law enforcement agencies in recent years have been frequently targeted by ransomware attacks, in which a perpetrator virtually locks up a victim’s computer files or system and demands payment to release them.The prevalence of cyberattacks — which can cause physical damage or far-reaching disruption — and less severe online trickery, such as stealing passwords, has given law enforcement agencies more experience at fending off efforts to take down their websites or access critical information. But hackers adapt too, and governments with fewer resources than private companies often struggle to keep up, said Morgan Wright, chief security officer for the cybersecurity company SentinelOne.“The biggest concern they have right now is the safety of their communities, the safety of their officers,” Wright said of how law enforcement agencies view cyberthreats amid large demonstrations and unrest. “But if you look at what underpins everything we use to communicate, collaborate and operate, it’s all technology.”As large protests gathered steam after the May 25 death of Floyd, a handcuffed black man who died after a white Minneapolis police officer used his knee to pin his neck down for several minutes, Minnesota Gov. Tim Walz said state networks had been targeted. He described the activity as a “a very sophisticated denial of service attack.”But experts said the strategy of bombarding a website with traffic is common and doesn’t always take a high level of skill, counter to Walz’s description. Minnesota’s Chief Information Officer Tarek Tomes later said state services weren’t disrupted.But the efforts got a lot of attention, partly due to unverified online claims that Anonymous was responsible after years of infrequent activity. The decentralized group largely went quiet in 2015 but is still known globally based on headline-grabbing cyberattacks against Visa and MasterCard, the Church of Scientology and law enforcement agencies.Twitter users also made unverified claims that Anonymous was behind recent intermittent outages on the city government’s website in the Texas capital of Austin. Their posts indicated that the disruption was retribution for police officers shooting a 20-year-old black man in the head with a bean bag during a May 31 protest outside of police headquarters.The injured protester, identified by family as Justin Howell, remained hospitalized Wednesday in critical condition.The city’s IT department was looking into the site’s issues, but a spokesman said Monday that he couldn’t provide any information about the cause. He said the website was still experiencing a high volume of traffic.“You should have expected us,” an account purporting to be Anonymous’ posted on Twitter. It also warned that “new targets are coming soon.”The collective’s approach — anyone can act in its name — makes it difficult to verify the recent claims of responsibility. But Twitter accounts long affiliated with Anonymous shared them, said Gabriella Coleman, a professor at McGill University in Montreal who has studied the Anonymous movement for years.People with more advanced and disruptive hacking skills often drove peak instances of attention for Anonymous, and it’s not clear whether that type of activity will resume, she added.“There’s a lot of things going on in the background, people are chatting,” Coleman said. “Whether or not it materializes is another question. But certainly people are kind of aroused and talking and connecting.”___Foody reported from Chicago.

As President Donald Trump’s chances of re-election are sagging on Wednesday, the president declared himself a winner in the presidential election on Wednesday despite projections showing he is trailing Joe Biden in the Electoral College.As of Wednesday evening, Biden holds a 248-214 advantage in the Electoral College. Biden also holds an advantage in Michigan, Arizona, and Nevada. If Biden hangs on and wins those states, he’ll have a projected 270 Electoral College, which is exactly the number needed to win.Twitter has recently updated its policy regarding misinformation involving the election, and as of 2 p.m. ET Thursday, Trump had his Twitter account flagged eight times for misinformation. 709
