Markey Concerned Trump Might Fire Mueller, Refuses to Address Russian Dossier

Massachusetts's junior U.S. senator, Ed Markey, told MSNBC's Andrea Mitchell on Monday that he's worried President Donald Trump may move to fire special prosecutor Robert Mueller, whose investigation into allegations of Russian-driven election collusion has now resulted in the indictment of a former Trump campaign manager and the guilty plea of a campaign underling. 

"This is clearly a major first step and we have to make sure that President Trump does not fire Robert Mueller, because that would be clearly something that he would considering right now to shut down this investigation, which he has been trying to do from its very inception," the Malden Democrat told Mitchell. "The president continues to argue that the whole Russian investigation is a hoax, and if he believes that, then he would seriously consider firing Robert Mueller, he would seriously consider giving a pardon to Paul Manafort or Rick Gates, and either one of those actions would trigger a major Constitutional crisis in the United States."
