Former Vice President Joe Biden slammed President Trump in a CNN interview.

Former Vice President Joe Biden on Tuesday slammed President Trump on a wide range of issues, including his attack on the FBI.
During an exchange with CNN's Chris Cuomo regarding the president's "treason" remark, Biden also called Trump "a joke."
In front of an audience that had showed up to hear Trump talk about the tax legislation benefits on Monday, the president mentioned that he noticed the lack of applause by Democrats during his State of the Union address.
"Can we call that treason? Why not?" Trump went on to say, "I mean, they certainly didn't seem to love our country very much."
Amid Biden's criticism of this comment, when Cuomo interrupted him and said that the White House says the president was just joking, the former vice president replied, "let me tell you, he's a joke."
Biden has been an outspoken critic of Trump.
In November, the former vice president stated during an appearance in Miami, "I think it's one of the most dangerous times in modern history."
And on 'The Late Show with Stephen Colbert,' Biden said of the sitting president's term, "I think it will, God willing, go down as the single exception in American history."
