'Shiver down the spine': Reporter explains which witness keeps Trump up at night

He's the White House key master.

CBS Correspondent Scott MacFarlane suggests that the immunity Mark Meadows' took in exchange for testifying in the federal presidential election subversion trial, spells big trouble for Trump and his inner sanctum.

"Mark Meadows, according to my contacts on the Jan. 6 [House Select] Committee, has the keys to the castle," he said, appearing opposite co-host Mark McKinnon in a promo of an upcoming episode of Showtime's "The Circus".

He continued: "One of their top investigators says there's nobody more important to talk to than Mark Meadows by leaps and bounds.”

According to MacFarlane's sources close to the committee, they tell him that, because of both Meadows' text messages and data they gleaned from him — "he has potentially the most damning evidence in any investigation of Donald Trump."

Meadows in the waits to potentially give up the goods on his former boss, MacFarlane suspects, is leading to many sleepless nights in Mar-a-Lago because he knows what alleged action and also inaction took place on behalf of the 45th president on Jan. 6, 2021.

"Him talking to the special counsel has got to send a shiver down the spine of Trump's team and likely the former president himself," he said.
