MSNBC's Morning Joe: ‘Spygate’ tweets prove Mueller 'scares the ever-living hell’ out of Trump

President Donald Trump lashed out at the investigation that's continuing to engulf his presidency -- and MSNBC's Joe Scarborough said the tweets betray his fear.

The "Morning Joe" host responded to the president's social media posts Wednesday morning, which veered from angry denials of Russia collusion and cheerful shout-outs to Fox News commentator Tomi Lahren.

"I don't really know where to begin," Scarborough said, laughing. "'Spygate?' I mean, you have a guy that Donald Trump says is running his foreign policy getting drunk and talking to the Australian ambassador and bragging about contacts with the Russians, and the FBI is tipped off by the Australian ambassador and they start moving forward."

That foreign policy adviser, George Papadopoulos, has pleaded guilty to lying to FBI agents as part of the special counsel probe, and a business partner of Trump's attorney Michael Cohen has also accepted a plea deal -- and both men have agreed to cooperate with investigators.

"There are still people who actually can think clearly in this country," Scarborough said, "and for those who can, it's very obvious that Robert Mueller is getting closer and closer and closer to something that scares the ever-living hell out of Donald Trump. Now he is apparently responding today to a plea deal by the taxi king yesterday that is going to take down his fixer, and Donald Trump obviously now unbelievably fearful that it's going to take him down as well."
