MSNBC host Rachel Maddow previewed a new documentary she produced on businessman Lev Parnas, in which he said he was “sorry” for investigating the Biden family’s connection to Ukraine.

Maddow argued the release of her documentary on Parnas, From Russia with Lev, tells “a really important story” about “what happens when crooks take over the White House” and claimed voters “considering” voting for former President Donald Trump needed to know it. Parnas, a former associate of Rudy Giuliani, was one of four people charged in October 2019 in a four-count indictment that stated they conspired to violate the ban on foreign donations and contributions in connection to U.S. elections, with Parnas later sentenced to prison for fraud and campaign finance crimes.
