This week is shaping up to be a critical one for retired Lt. Gen. Michael Flynn.

"Breaking News: sources tell me [Flynn] will be completely exonerated this week. It was a total fraud. A Set up. More tomorrow," tweeted Fox Business host Maria Bartiromo on Sunday.

In another tweet teasing Monday's edition of her weekday morning show, Mornings with Maria, Bartiromo included the hashtag "#GeneralFlynn," along with a list of her guests, including multiple lawmakers.

Earlier in the day, on her weekend Fox News show, Sunday Morning Futures, Bartiromo noted during a conversation with Rep. Devin Nunes that it would be an "important" week for Flynn.

The California congressman, who is the top Republican on the House Intelligence Committee, said he suspects that a filing submitted to the court in Flynn's case on Friday contained exculpatory evidence and noted that U.S. Attorney for the Eastern District of Missouri Jeffrey Jensen, who was selected by Attorney General William Barr in January 2020, is reviewing the Flynn case.

CBS News senior investigative correspondent Catherine Herridge also reported on Sunday that Friday's filing will be "important" for the coming days.

"Drawing attention Friday filing Flynn case @CBSNews told important for days ahead. AG Barr directed Missouri US Attorney to review FBI personnel 'communications and notes,' in part, to determine whether key evidence withheld. Docs under seal but may change," she tweeted.

Last week, the legal team for Flynn, led by Sidney Powell, claimed newly released evidence showed the former Trump national security adviser was “set up” by the FBI.

Flynn, 61, is fighting to dismiss the government's case against him, which stems from the Russia investigation.

He pleaded guilty in December 2017 for lying to investigators about his conversations with Russian diplomat Sergey Kislyak regarding sanctions on Russia and a United Nations resolution on Israel. But in January, he told the U.S. District Court in Washington, D.C., that he was "innocent of this crime." He filed to withdraw his guilty plea after the Justice Department asked the judge to sentence Flynn to up to six months in prison, though afterward, the department said probation would also be appropriate. Powell is pressing for the dismissal of his case by arguing the FBI unfairly treated Flynn.
