Bad news: There is a small chance an asteroid will collide with Earth. The good news: Mankind has more than 115 years to prepare for it. According to a Washington Post report, NASA is preparing for possible tactics to deflect the asteroid Bennu, which will approach Earth Sept. 21, 2135. As of today, NASA rates Bennu's chance of striking Earth at one-in-2,700.The asteroid is roughly 1,600 feet in diameter, and would not be an Earth-ending event if it struck. But that doesn't mean it couldn't cause damage, especially if it struck near a populated area. Bennu is likely dozens of times larger than the object that struck near Chelyabinsk, Russia in 2013, causing hundreds of injuries, and thousands of broken windows. The event caused nearly million in damage to roughly 7,000 buildings. The 2013 event shows that even small objects are capable of causing massive damage. In 2016, NASA launched OSIRIS-REx, which will land on the asteroid and bring back samples. The information gathered could help NASA decide what steps it would take to deflect the asteroid. According to the Washington Post, NASA is working on a plan called the Hypervelocity Asteroid Mitigation Mission for Emergency Response, or HAMMER. NASA's HAMMER plan could involve using a nine-ton bulk impactor to push Bennu out of Earth's path. Another idea would be straight out of the movie "Armageddon," using a nuclear-type device to move the asteroid. A NASA engineer involved in the study told the Washington Post all of these ideas are theoretical. “We’re doing these design studies to prepare ourselves, so if we do find a threatening object, we’re better prepared to deal with it,” Brent W. Barbee, NASA engineer, told the Post.To read the Washington Post's full report, click here.  1855

BABSON PARK, Fla. — A second university in Polk County, Florida has announced that they will be joining a program that will allow its staff and faculty to legally carry guns on campus.The announcement comes just eight days after a gunman opened fire on a Florida high school killing 17 people.The Polk County Sheriff's Office, in partnership with Webber International University, is establishing the Sheriff's Sentinel Program to enhance the safety of an already safe and secure community of students, faculty, staff, and guests at the University's campus in Babson Park, Florida."Prayers are not enough," Polk County Sheriff Grady Judd said in a press conference on Thursday. “The only thing that stops a bad guy with a gun is a good guy with a gun."Sheriff Judd explained that each teacher or staff member will have to go through extensive training through the program before they are given a gun."My babies — your babies — are in that classroom, and that active shooter is coming down the hallway with that thousand yard stare and that gun in their hand, do you want somebody to step out and stop him? Or do you want him to go into the classroom and slaughter your babies?" 1194

Attorney General Jeff Sessions' private attorney said Wednesday that the attorney general is not under investigation by special counsel Robert Mueller's office for perjury related to statements made at his confirmation hearing.In response to?an ABC News report saying that now-dismissed FBI official Andrew McCabe had authorized an investigation into whether Sessions lied to Congress about his contacts with a top Russian diplomat, attorney Chuck Cooper said Mueller's office has informed him that Sessions is not being investigated over his testimony."The special counsel's office has informed me that after interviewing the Attorney General and conducting additional investigation, the Attorney General is not under investigation for false statements or perjury in his confirmation hearing testimony and related written submissions to Congress," Cooper said in a statement to CNN.The special counsel's office declined to comment.A source close to Sessions said he was not aware of any investigation into possible perjury when McCabe was fired last week.CNN reported in January that Sessions was questioned for several hours by Mueller's team as part of the investigation into Russian election meddling and any possible collusion with President Donald Trump's team. A source familiar with the matter told CNN that Cooper was unaware of any possible perjury investigation related to Sessions before it was revealed by the ABC report.Sessions has repeatedly said that he didn't mislead senators or lie under oath.Vermont Democratic Sen. Patrick Leahy and then-Minnesota Democratic Sen. Al Franken wrote to then-FBI Director James Comey last March asking the FBI to investigate Sessions' testimony. The ABC report said McCabe opened the probe after the letter.A representative for McCabe declined to comment on the ABC story, which said top lawmakers of both parties were informed about the probe in a private briefing from McCabe in May, where Deputy Attorney General Rod Rosenstein also attended.A spokesman for Leahy said Wednesday that the senator was "not otherwise made aware of an investigation" into Sessions for perjury and that the FBI had declined to "confirm or deny the existence of an investigation" as of May 2017.Sessions confirmed last year that he met with Sergey Kislyak, the former Russian ambassador to the US, on two occasions: once on the sidelines of the Republican National Convention in July 2016, and then in his office in September 2016, when Sessions was a member of the Senate Armed Services committee.Sessions did not, however, mention either meeting during his confirmation hearing last January -- a fateful choice that has cast a long shadow over his tenure at the Justice Department.The critical exchange took place in January 2017, when Franken read from a CNN story about the dossier on Trump and Russia, and asked Sessions: "If there was any evidence that anyone affiliated with the Trump campaign communicated with the Russian government in the course of this (2016) campaign, what would you do?"Sessions responded: "I'm not aware of any of those activities. I have been called a surrogate at a time or two in that campaign and I did not have communications with the Russians."He further replied, "no," when asked whether he had been "in contact with anyone connected to any part of the Russian government about the 2016 election, either before or after Election Day" in his Senate questionnaire.For over a year, the attorney general has faced scrutiny from lawmakers on Capitol Hill about those portions of his testimony.After his confirmation hearing, The Washington Post reported on Sessions' undisclosed meetings with Kislyak, prompting members of Congress to call for Sessions to resign or step aside from overseeing the FBI's investigation into potential coordination between Russian officials and the Trump campaign.Kislyak, a career diplomat, was considered to be one of Russia's top spies and spy-recruiters in Washington, according to current and former senior US government officials -- though Russian officials dispute that characterization. Ultimately, Sessions recused himself from all investigations related to the 2016 campaign and Mueller was appointed special counsel.Sessions has steadfastly maintained that he was honest in his testimony."It simply did not occur to me to go further than the context of the question and list any conversations I may have had with Russians in routine situation, as a I had with numerous other foreign officials," Sessions said at a Senate Intelligence Committee hearing last June."I have never met with or had any conversations with any Russians or any foreign officials concerning any type of interference with any campaign or election," he added.Sessions later said he did not recall a third alleged private meeting with Kislyak on April 27, 2016, at the Mayflower Hotel in Washington, where then-candidate Trump delivered his first major foreign policy speech.Finally, in November, Sessions testified that he vaguely remembered a March 2016 meeting with Trump campaign aide George Papadopoulos, but said he had "no clear recollection of the details" of what was said at the time. Papadopoulos pleaded guilty last fall to making false statements to investigators about his interactions with foreign officials close to the Russian government."After reading (Papadopoulos' account), and to the best of my recollection, I believe that I wanted to make clear to him that he was not authorized to represent the campaign with the Russian government, or any other foreign government, for that matter," Sessions told House members. "But I did not recall this event ... and would gladly have reported it had I remembered it, because I pushed back against his suggestion." 5791

  

As the chaotic 2020 presidential race enters its final stretch, Vice President Mike Pence and Democratic vice presidential nominee Kamala Harris will square off in a debate at 9 p.m. ET on Wednesday in Salt Lake City.The COVID-19 pandemic will be at the forefront of Wednesday's debate — both literally and figuratively. As the nation seeks more info regarding President Donald Trump's health amid his COVID-19 infection, both Pence and Harris have agreed to allow debate officials to install plexiglass shields next to their podiums.Harris' staff initially requested the shields, citing the COVID-19 outbreak that's infected several White House staffers. After initially saying the shields were not necessary, Pence's staff agreed to the change on Tuesday night.The Associated Press reports that both Harris and Pence tested negative for the virus on Tuesday morning.Wednesday's debate will be broken into nine 10-minute segments. Each candidate will have two minutes to answer a question from moderator Susan Page, and the other candidate will then have two minutes to respond.The 2020 VP debate will likely hold more important than in years past, given the ages of Trump and his opponent, former Vice President Joe Biden. Trump, 74, was the oldest candidate ever to be elected president in 2016, and Biden, 77, is three years older than Trump. Amid a global pandemic, voters may be taking a keen interest in each administration's chain of command.The Trump campaign is banking on a strong performance from Pence amid slumping poll numbers. An average of national polls shows Biden leading Trump by about nine percentage points, and a recent CNN poll released this week showed that 57% of likely voters favored Biden, compared to just 41% for Trump.Wednesday may also mark the last debate for at least a few weeks. There are two more presidential debates scheduled between now and Nov. 3, but Trump's COVID-19 diagnosis has put the status of the second debate — currently scheduled for a week from Thursday — in doubt. Trump says he still plans to participate, but Biden has said the debate should not take place if the president is still infected with the virus due to safety concerns. 2196

  

ATLANTA — The long-standing dispute over voting rights and election security has come to a head in Georgia.The state's messy primary and partisan finger-pointing offer an unsettling preview of a November contest when battleground states could face potentially record turnout.According to The Associated Press, many Democrats are blaming Georgia's Republican governor, Brian Kemp, and Republican secretary of state, Brad Raffensperger, for hours-long lines at polling stations. Republicans are blaming local Democratic officials in Atlanta, particularly in areas with large numbers of racial minorities, which saw some of the longest lines in the state.Georgia's Tuesday elections were plagued with a series of problems caused by the coronavirus pandemic, which forced the closure of dozens of polling stations across the state. Fewer polling stations resulted in long lines at stations that remained open.The pandemic also caused an increase in requests for absentee ballots — which some voters claimed they never received. Some of those voters then stood in line for hours hoping to cast an in-person ballot, only to be told they could not because they had requested a mail-in ballot that they never received.The election was further exacerbated by the use of new voting machines, which some precincts had trouble operating. Some polling stations had trouble turning on or logging into machines, and voters were forced to stand in line while workers waited for technical support.As of Wednesday morning at 7:30 a.m. ET, many races of national importance were still too close to call, with only 24% of the state's 2,354 voting precincts reporting complete results. In the Democratic Senate primary, John Ossoff held 46% of the vote — short of the 50% he needed to win to avoid a runoff in August.The election issues raise the specter of a worst-case scenario: a decisive state, like Florida and its "hanging chads" and "butterfly ballots" in 2000, remaining in dispute long after polls close.That would give President Donald Trump, presumptive Democratic presidential nominee Joe Biden, and their supporters a chance to offer competing claims of victory or raise questions about the election's legitimacy, further dividing an already roiled electorate. 2260
