Congress swore in President-elect Joe Biden early Thursday morning, a day after violence, multiple deaths, and unprecedented chaos erupted in Washington D.C. by an angry mob of Trump supporters. Biden calls yesterday "one of the darkest days in the history of our nation" and "an assault on the rule of law." He urges people, "don't call them protesters, they were a riotous mob, insurrectionists, domestic terrorists," says Biden. Former Presidents Barack Obama, George W. Bush, Bill Clinton and Jimmy Carter on Wednesday each condemned the mob of armed rioters who stormed the U.S. Capitol. Obama said the attack will be remembered as "a moment of great dishonor and shame" and that his successor, President Donald Trump, is the primary culprit for not calling off the attack. He also faulted the Republican Party, lawmakers, and the right-wing media for the role they played in casting doubt on the integrity of the election results. President George Bush also urged people upset about the recent elections to stand down for the sake of American democracy, “It is a sickening and heartbreaking sight,” Bush said in a statement. “This is how election results are disputed in a banana republic, not our democratic republic.” Several White House officials handed in their resignations today after the domestic attack, including chief of staff Mick Mulvaney and the top European and Russian official Ryan Tully. Vice President Mike Pence, the most important of Trump's cabinet, officially pronounced Biden as President-elect and Kamala Harris as Vice President-elect on Thursday to be sworn in and assume office at noon Eastern on January 20. Facebook announced that Trump is banned on Facebook and Instagram at least until his term is over for inciting violence, and Twitter banned him from tweeting for at least 12 hours. Trump has been accused by many pundits as trying to start a civil war over a fair election to avoid facing dozens of high-profile lawsuits that he and his family will have to face as citizens starting next month. Trump has a net worth of $2.5 billion and at least $1 billion in debt, according to Forbes.
