Tuesday’s virtual Democratic National Convention included the official nomination of Joe Biden for president, and a pitch from Biden's wife Dr. Jill Biden and two former Democratic presidents.Tuesday’s theme was "The Leaders We Are," and in addition to the former presidents speaking in favor of a Biden presidency, Democrats tried to once again portray Biden as a bipartisan leader.Colin Powell endorses BidenColin Powell, who served in several Republican administrations, most recently as George W. Bush’s secretary of state, delivered a full-throated endorsement of Biden on Tuesday. Despite his GOP ties, Powell has previously endorsed Democrats Barack Obama and Hillary Clinton.On Tuesday, he made the case that Biden is prepared to lead the US military.“Our country needs a commander in chief who takes care of our troops in the same way he would his own family,” Powell said. “For Joe Biden, he doesn't need teaching. It comes from the experience he shares with millions of military families, sending his beloved son off to war and praying to God he would come home safe. Joe Biden will be a president that we will all be proud to salute with Joe Biden in the White House.”While not mentioning President Donald Trump by name, Powell said that the president has divided the US.“What a difference it will make to have a president who unites us, who restores our strength and our soul,” Powell said.Meanwhile, the president’s campaign slammed Powell and Biden on Twitter for green lighting the war in Iraq.It was no mistake following Powell’s statement was a video highlighting the relationship between Biden and Republican Sen. John McCain, who died in 2018 from brain cancer. McCain’s wife Cindy participated in a video montage of the Biden-McCain friendship.Former President Bill Clinton slams Trump’s COVID-19 responseFormer President Bill Clinton, who has been a speaker at every Democratic National Convention for the last four decades, decried Trump’s response to the coronavirus. During his remarks, Clinton said that Trump has denied responsibility for the effects COVID-19 have caused in America.“At first he said the virus was under control and would soon disappear,” Clinton said. “When it didn't, he was on TV every day bragging on what a great job he was doing, while scientists waited to give us vital information. When he didn't like the expert advice he was given, he ignored it.“Only when COVID exploded in even more states did he encourage people to wear masks. By then many more were dying. When asked about the surge in deaths, he shrugged and said, It is what it is.' But did it have to be this way? No.”On Tuesday, the United States’ death toll from coronavirus-related illnesses surpassed 171,000.Jill Biden speaks from former classroomJill Biden spoke live from Brandywine High School in Wilmington, Delaware, where she was an English teacher from 1991 to 1993.The former second lady and wife of the Democratic nominee made a personal pitch, vouching for Biden’s character.She spoke on the tragedies her husband has faced in life, losing his previous wife and infant daughter in 1972, followed by the death of his son from brain cancer in 2015.“How do you make a broken family whole? The same way you make a nation whole: with love and understanding, and with small acts of kindness,” Dr. Biden said. “With bravery and unwavering faith.""We're seeing that our differences are precious and our similarities infinite. We have shown that the heart of this nation still beats with kindness and courage. That's the soul of America Joe Biden is fighting for now,” she added. 3605

US President Donald Trump says China has agreed to cut tariffs on cars it imports from the United States.Trump made the announcement in a tweet late Sunday in the United States, saying Beijing will "reduce and remove" the tariffs, which currently stand at 40%. He didn't specify when the change would happen or what the new tariff level would be.Chinese Foreign Ministry spokesman Geng Shuang declined to comment Monday on Trump's statement, referring questions to "the relevant authorities." The Chinese Commerce Ministry, which typically makes announcements regarding tariffs, didn't respond to a faxed request for comment.Trump's tweet comes after he and Chinese President Xi Jinping agreed on Saturday to hold off on further tariffs in the trade war between the two countries for the time being. But the Chinese government has made no mention of cutting car tariffs as a result of the meeting between the two leaders in Buenos Aires.Xi announced in a speech in April that China would cut tariffs on imported cars this year. His government followed through on that promise three months later, reducing them from 25% to 15%.But just days later, it imposed new additional tariffs of 25% on American-made passenger vehicles, one of the groups of products it targeted early in the trade warwith the United States.The move has hurt the profits of major automakers like BMW (BMWYY) and Daimler (DDAIF), the owner of Mercedes-Benz. The German companies both ship SUVs to China from manufacturing plants in the United States.Shares in BMW jumped more than 6% on Monday morning in Frankfurt following Trump's tweet, while Daimler's stock leaped more than 5%.Tu Le, the head of research firm Sino Auto Insights, highlighted the lack of specifics in Trump's tweet. 1804

United States' Ambassador to the United Nations Nikki Haley said Sunday the Trump administration will announce more sanctions against Russia on Monday.On CBS's "Face the Nation," Haley said the Treasury Department will announce the new sanctions and insisted the US has sent "a strong message" about the use of chemical weapons."You will see that Russian sanctions will be coming down," said Haley, reiterating what she said earlier on Fox News. "Secretary Mnuchin will be announcing those on Monday, if he hasn't already."While insisting the action taken early Saturday morning in Syria was "a very strong attack on the chemical weapons program," Haley hit back on more hawkish critics who argue the US didn't go far enough because it did not change the balance of power in the long-running Syrian civil war."Our job was never to take Assad out," Haley said, referring to Syrian President Bashar al-Assad. She added that the conflict must ultimately be resolved through a UN-led political process. "Our job was never to start a war."Haley also said the response by the Trump administration was "cumulative," taking into account not only the recent chemical weapons attack in Douma, but also other, smaller, attacks. The action, she added, came after diplomatic options had been exhausted.When asked on "Fox News Sunday" about "how our relationship with Russia has changed this week," Haley said that relations are "very strained.""If you look at what Russia is doing, they continue to be involved with all the wrong actors, whether their involvement in Ukraine, whether you look at how they are supporting Venezuela, whether you look in Syria and their way of propping up Assad and working with Iran, that continues to be a problem," Haley said, adding that the use of a poisoning agent against a spy in England is "another issue."She added that Russia is feeling the effects of US actions including "the sanctions that are continuing to happen, which you'll see again on Monday.""Right now they don't have very good friends and right now the friends that they do have are causing them harm," Haley said, referring to Russia. "I think they're feeling that."Haley also said that although "it is all of our goal to see American troops come home," the United States won't leave Syria before accomplishing President Donald Trump's three major goals: eliminating the threat of chemical weapons attacks in Syria, defeating ISIS "completely and wholly," and making "sure that we had good grounds to watch what Iran was doing. ...""What (Trump) has done is talked to our allies and said they need to step up more. They need to do more. And it shouldn't just be us doing it. I think that's the right approach," Haley added. "But be very clear, if we leave, when we leave, it will be because we know that everything is moving forward." 2834

URBANA-CHAMPAIGN, Ill. – As colleges and universities are tasked with safely beginning classes, researchers at one school are ramping up testing. But they're putting away the nasal swab in exchange for a test they say can be scaled to perform thousands of tests a day with turnaround in just hours.College junior Alliyah Rumbolt-Lemond is already back on campus and regularly testing for COVID-19.“I know if you have in-person classes, you're going to be on campus, you have to get tested twice a week,” she says.The college junior is one of the more than 51,000 students at the University of Illinois at Urbana-Champaign returning to school during the pandemic, posing a logistical challenge for administrators.“It was very daunting,” said U of I chemistry professor Marty Burke.He was part of the team of university researchers who developed a two-step saliva-based COVID-19 test to tackle the problem.“We called this our ‘target, test and tell’ initiative, overall collectively described as a ‘Shield.’”The Shield Initiative needed to be scalable, and unlike the four-step nasopharyngeal swab tests, not vulnerable to supply chain bottlenecks.“It's a very powerful concept that if we can get to that fast, frequent testing, we really could get control of the situation,” said Burke.A quick stop on route to class or work, integrated with local health care agencies, students receive results on an app within hours, not days.“It takes about five to ten minutes to submit your saliva sample and then the results are typically back on your phone within three to six hours,” said Burke.The university’s veterinary school diagnostic lab has been converted into a full-scale human COVID-19 testing facility. It’s capable of processing some 10 to 20,0000 saliva tests per day.“I want to hang out with friends and do it the right way, like following CDC guidelines,” said Alliyah. “But I feel more comfortable saying ‘hey when's the last time you got tested?’”A total of 20 testing sites with 40 stations are set up across campus. Users can even get exposure notifications if they’ve been in contact with someone who tests positive.“If someone tests positive then same day that person is isolated,” said Burke. “Which we think is critical for ultimately the efficacy of the testing program.”They’ve published a pre-print paper on their COVID-19 saliva test, which is undergoing peer review and are seeking FDA approval.For students like Alliyah, it’s one-stop piece of mind.“It makes you feel like I'm safer on campus because even though we only have to get tested twice a week you can get tested every day the testing site is open if you wanted to.” 2653
