BUSTED: Trump also tried to torpedo investigation into Russian election interference in 2016

One of the lesser known details in special counsel Robert Mueller's report is that President Donald Trump did not just attempt to shut down the investigation into himself, but he also attempted to kill the investigation into how Russia interfered in the 2016 presidential election, a national security expert explained on MSNBC.

MSNBC anchor Chris Hayes drew attention to a part of the report mentioning former Trump campaign manager Cory Lewandoski, "which has not gotten a lot of attention."

"According to Lewandowski, Trump asked him to bring a note telling Jeff Sessions to give a speech that would say the following," Hayes noted.

"Now a group of people want to subvert the Constitution of the United States," Sessions was supposed to say in the speech. "I am going to meet with the special prosecutor to explain this is very unfair and let the special prosecutor move forward with election meddling for future elections so it can’t help in future elections."

"This is an attempt to shut down the whole thing," Hayes said.

"This is an attempt, not just to shut down the investigation into him, into Trump, but also an attempt to shut down the investigation into the Russian hacking," Wheeler noted.

"No one gets this. No one gets that in the summer of 2017 at the same time that Trump had just met for the first time with Vladimir Putin in this kind of crazy meeting in the G-20," she explained. "He went to Lewandowski -- dictated to him -- it's right there in the report and made him write it down and Lewandowski was like, 'he's never dictated anything to me before.'"

"He makes him write it down and in that paper, he says, go tell Sessions to shut down the investigation into the Russians who hacked us in 2016. Mueller can investigate what’s going to happen, 2018 and 2020, but not in 2016," Wheeler noted. "That’s crazy and no one knows that Trump tried to shut down the entire investigation, not just his side, but the Russian side as well."
