“Late Show” host Stephen Colbert compared President Trump on Tuesday to a “reminiscing” grandfather after Trump called the Justice Department part of the “deep state,” a reference to a conspiracy theory about a behind-the-scenes bureaucracy controlling the government.

“Crooked Hillary Clinton’s top aid, Huma Abedin, has been accused of disregarding basic security protocols. She put Classified Passwords into the hands of foreign agents,” Trump tweeted earlier Tuesday. “Remember sailors pictures on submarine? Jail! Deep State Justice Dept must finally act? Also on Comey & others.”
