'Rantings of an increasingly isolated and worried individual’: Nicolle Wallace explains cause of Trump’s Twitter meltdown

MSNBC host slammed the "fake news" coming from President Donald Trump's Twitter feed on "Deadline: White House" Tuesday.

"It's no coincidence that as the pace of indictments and charges from the Mueller probe take on the feel of a drumbeat, Donald Trump's Twitter feed reads like the rantings of an increasingly isolated and worried individual," Wallace explained.

"News today that Mueller has charged a lawyer who once worked with former Trump campaign manager Paul Manafort for lying to investigators," Wallace reported. "The son-in-law of a Ukrainian Russian oligarch named in the controversial Donald Trump dossier who's accused of lying to investigators in the Russia investigation."

"This is as Donald Trump blusters away on Twitter about the significance of Friday's 13 indictments of Russian nationals for their role in meddling in the 2016 presidential election," the host noted.

Wallace had particular contempt for the falsehoods in one Trump tweet, where he falsely compared his record to that of former President Barack Obama.

"The fake news is that part of that tweet where President Trump claims to have been tougher on Russia," Wallace declared.
