President Donald Trump has been involved in an extraordinary exchange with a CNN reporter at a press conference, the day after the US midterm elections saw his chances of advancing his legislative agenda hampered.
CNN reporter Jim Acosta, a frequent critic of the President, once again drew his ire when asking about the Russia inquiry into possible 2016 election interference.
The president spoke over Acosta, and demanded he hand over the microphone.
He said the investigation is a "hoax", before stepping away from the podium.
When he returned, he them said "I tell you what, CNN should be ashamed of itself, having you working for them," and then, "you are a rude, terrible person".
He later called Acosta an "enemy of the people".
NBC's Peter Alexander came to Acosta's defence, prompting Trump to say"well, I'm not a big fan of yours either. You aren't best."
Earlier, President Trump warned House Democrats about spending the remaining years of his presidency investigating him and the administration.
Trump said at a post-election news conference that Democrats and Republicans should set aside partisanship to work together for the American people.
Democrats won back control of the House. Many have threatened to use the subpoena power they will gain in January to investigate Trump and administration actions.
Trump says he's been hearing about investigations since he began running for president and refers to it as "investigation fatigue."
He says he will respond in kind if House Democrats flood his administration with subpoenas and government will come to a halt. Trump adds that Democrats have "nothing, zero" on him.
