Dem Lawmaker Warns Trump Against Firing Mueller

The top Democrat on the House Intelligence Committee is calling on Congress to "unite to stop" President Donald Trump if he tries to fire Deputy Attorney General Rod Rosenstein or Special Counsel Robert Mueller.

Mueller is investigating Russian interference in U.S. elections and possible Russian ties to the Trump campaign. Trump confirmed in a tweet Friday he was under investigation and appeared to take aim at Rosenstein, calling the investigation a "witch hunt."

California Rep. Adam Schiff says it's clear that Trump "believes that he has the power to fire anyone in government he chooses and for any reason."
