Sanders added:

"He is suing the media who criticizes him. He is going after law firms who have clients who were against him. He's going after universities that teach courses that he doesn't like. He's threatening to impeach judges who rule against him. And he's usurping the powers of the United States congress. This guy wants all of the power. He does not believe in the constitution. He does not believe in the rule of law."

Pointing to the Republican-led House and Senate, Sanders went on to say that the future of the US "rests with a small number of Republicans in the House and Senate who know better, who do know what the constitution is about".

"It's high time they stood for our constitution and the rule of law," Sanders said."
