MSNBC legal analyst highlights specific Trump tweets Mueller can use to pin obstruction on Trump

It was announced Thursday that special counsel Robert Mueller is now looking into President Donald Trump's tweets as part of an investigation into possible obstruction of justice. MSNBC's legal analyst did a line-by-line breakdown of some of the most egregious Twitter mistakes made by the self-described billionaire since becoming president.

NBC News legal analyst Danny Cevallos explained that the prosecution must demonstrate first that Trump did send those tweets and it wasn't merely a staffer going rogue. The investigators will then compare it to the daily schedule. For example, did Trump tweet that on a day he met with former FBI Director James Comey?

Host Chuck Todd walked through specific tweets asking Cevallos to indicate whether it could be considered evidence of obstruction of justice.

First was the tweet Trump sent just after firing Comey.

"It was somewhat benign," Cevallos explained. "But now you get into this -- the nastier tweet after Comey is terminated and you start putting all of these together to show that, No. 1, Trump is probably putting up some kind of implicit threat. 'Comey better hope there are no tapes.' It's even more so if there are no tapes. What if it's just a bald threat for Comey to keep it quiet. If it was something to induce Comey to remain silent, especially in the face of any duty to speak, like, for example, in front of a grand jury or Congress, then these are the kinds of things that Mueller will find very interesting, irrespective of whether or not they're eventually way down the road."

There was another tweet that Cevallos said was his "favorite tweet of the year," because ex-lawyer John M. Dowd confessed to writing it.

The legal analyst explained that it's a dangerous practice to claim that your lawyer is writing tweets because "someone's attorney can be imputed to the client." Secondly, it tests the credibility of Dowd for authoring Trump's tweets, which contained misspellings.

Finally, "it contained what would be a very damaging statement as to criminal liability because it included the words Michael Flynn lied to the vice president and also the FBI, which if true suggests that President Trump was aware that Flynn was lying to the FBI, which is a crime," he continued. "So whether it's authored by Trump or his lawyers, it makes the lawyers look just galactically incompetent if they were authoring tweets that suggest criminal activity."
