Rep. Jamie Raskin (D-MD) appeared on CNN Thursday and said that psychiatric professionals are alarmed at President Donald Trump's apparent mental state and that he is showing signs of being "increasingly paranoid and delusional."

Raskin has proposed a bill calling for an investigative body to adjudicate whether or not Trump is mentally impaired and whether or not the 25th Amendment should be invoked.

"We're not mental health professionals, we're not psychiatrists, that's not our role," Raskin said, "but we do have a defined and important role under the 25th Amendment to the Constitution, which is to set up a body that could act with the vice president in the event of an emergency."

CNN's Jake Tapper asked Raskin how he can be so sure his politics and personal distaste for the president aren't coloring his perceptions.

Raskin said that many Republicans have "confided their doubts" about Trump's mental health to him.

"There a lot of things that are disturbing," he said, including Trump's denial that his voice was the one heard on the Access Hollywood and other "increasingly delusional behavior."
