I watched that. Schiff was being verbally attacked by a Republican reading from a long paper. I don't know when Schiff cut off the mike, if he did, but the Republican had gone on for a long time.
Trump wants him to resign, leave congress. That is typical Trump - he thinks he owns this country and can order people to do his will. We have a process to remove someone - it is called "election". If his district wants him out, they can vote him out. That is the House, and they have to run for office every two years.
Trump has also ordered the FBI/Justice Dept. to investigate the black male case in Chicago who made up he was attacked. He thinks he can tell the FBI to investigate any case in the country. That is an abuse of the FBI - he thinks he can make them investigate anyone he wants investigated. He also cannot toss out Schiff.
