CNN's Carl Bernstein tells Reliable Sources host Brian Stelter that people close to Trump are saying he's determined to shut down the Mueller investigation. BERNSTEIN: He's said that all along and he's determined to shut it down. Those who are closest to him will tell you it's very hard to stop his rages, especially in the last couple of weeks about Mueller, and as they say to me and others that he is determined to shut this investigation down. He hasn't quite figured out how to do it, but he's determined to do it.
