US President Joe Biden has criticized former President Donald Trump and his supporters as 'extremists'.
President Joe Biden said former President Donald Trump and his supporters threatened the "foundations of our state".
According to the AFP news agency, on Thursday night, the American president said in an address to the nation that "Donald Trump and his Republican supporters are extremists who are a threat to the foundations of our state."

Speaking in Philadelphia, considered the cradle of American democracy, Joe Biden launched an unusual verbal attack on Republicans who embrace Trump's "Make America Great Again" ideology. The US president urged his supporters to strike back.
Joe Biden said of Trump and his supporters that they "embrace anger." They thrive in chaos. They live not in the light of truth but in the shadow of lies.
President Biden said that "There is no place for political violence in America, never, never."
Last year, the US Capitol Hill in Washington was attacked by hard-line supporters of Donald Trump.
Beyond Capitol Hill, President Biden also cited a nationwide attack on abortion rights by hard-line conservatives.
He said, "There are fears that other freedoms, from contraception to same-sex marriage, will be taken away, and the Republican mega-forces are working to take this country backwards."
Joe Biden said that citizens must defend American democracy. These people are a threat to this country. Protect it and stand up for it.'
