Donald Trump has accused the FBI and the Democrats of treason, and threatened to have Attorney General William Barr investigate them.
He made the comments at a rally in Pennsylvania, where his supporters broke into chants of, "Lock them up."
At the same rally, Trump also remarked that Fox News had started "putting more Democrats on than Republicans", and added that "something strange is going on".
He appeared to be responding to the network's decision to screen a town hall event featuring Democratic candidate Pete Buttigieg.
Following these comments, the crowd proceeded to boo Fox News, which has up to now shown support for Trump.
Cal Thomas and Marion McKeone discussed this and more from the United States.
