U.S. President-elect Joe Biden and some former U.S. presidents have expressed shock and outrage at the storming of the U.S. Capitol in Washington by supporters of outgoing President Donald Trump on Wednesday. 

- Joe Biden called the violence an "insurrection" and demanded that Trump immediately goes on national television to urge his supporters to lift the siege of the Capitol. "Our democracy's under unprecedented assault," Biden said in his home state of Delaware. "The scenes of chaos at the Capitol do not reflect a true America," he added.

- Barack Obama: "History will rightly remember today's violence at the Capitol, incited by a sitting president who has continued to baselessly lie about the outcome of a lawful election, as a moment of great dishonor and shame for our nation."

- George W. Bush: "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." 

- Bill Clinton: "Today we faced an unprecedented assault on our Capitol, our Constitution, and our country," the former Democratic president said in a statement, adding that the attack was fueled by "four years of poison politics" and deliberate misinformation.  "
