MSNBC's Joe Scarborough went on an extended rant against "Moscow Mitch" McConnell for repeatedly blocking measures that would protect American democracy from Russian attacks.

The Senate majority leader blocked two election security bills twice this week, despite warnings from U.S. officials and former special counsel Robert Mueller that the Kremlin was actively engaged in efforts to interfere with the 2020 election -- and McConnell prevented the Obama administration from warning Americans about Russian meddling in 2016.

"Robert Mueller testified that not only did Russia try to interfere with our 2016 election and not only did Donald Trump's -- all of his intelligence community and Kirstjen Nielsen, when she was at Homeland Security, said Russia undermined American democracy in 2016," Scarborough said. "We remember back then the warnings came, but 'Moscow Mitch,' that being Mitch McConnell, of Moscow, Kentucky, actually blocked that and said he threatened the people that were going to try to get that information out to warn Americans."

Former special counsel Robert Mueller decided he could not indict President Donald Trump while he is in office, but that is not the only mechanism for legal accountability.

Former Obama administration acting Solicitor General Neal Katyal explained to MSNBC anchor Lawrence O'Donnell on Thursday how there is another option.

"Last night a former Watergate assistant special prosecutor, Jill Wine-Banks, made a point about indicting a president that had not occurred to me," O'Donnell noted, introducing a clip.

"The evidence of all the elements of the crime has been established and were he not protected by the Office of Legal Counsel -- an opinion by the way that I think is flawed constitutionally and legally -- I think it’s incorrect. It’s time for someone to challenge it or change it. It may take a state prosecutor indicting the president to take it to the Supreme Court for a decision and whether you can cover up your own crime and get away with it," she noted.

President Donald Trump can be indicted right now, a former top Republican prosecutor explained to MSNBC's Lawrence O'Donnell on Thursday.

The host of "The Last Word" interviewed Bill Weld, the former Republican governor of Massachusetts who is currently challenging the sitting president for the 2020 GOP nomination.

Prior to his career in elected office, Weld was a top federal prosecutor.

In 1981, Weld was nominated by Ronald Reagan to be the United States Attorney for Massachuttes. After receiving positive media coverage for his anti-corruption court victories, in 1986 Reagan promoted Weld to head the Criminal Division of the Department of Justice.
