Here's what Mueller will be able to prove now that he has the House Intelligence Committee transcripts: ex-prosecutor

A former federal prosecutor explained Wednesday that special counsel Robert Mueller will have more ammo than ever before now that he's gotten transcripts from the House Intelligence Committee's Russia probe interviews.

Joyce Vance, the former U.S. Attorney for the Northern District of Alabama, told her MSNBC co-panelists that Mueller has been given a "pregnant list" of transcripts from individuals like Steve Bannon, Donald Trump Jr., Jared Kushner, Brad Parscale and more.

Since Mueller now has those documents, he "can do two things," the ex-prosecutor said.

"He can compare it against evidence he has or testimony that he has taken himself," Vance explained, adding that the special counsel now "also has the physical document that he would need to trigger a prosecution."

"In other words, prosecutors don't indict people for perjury without an official transcript," she said. "They need it for evidentiary reasons in a courtroom."

House Republicans made a "last-minute play trying to avoid naming people to the committee so that these official transcripts couldn't be sent over to Mueller," the former federal prosecutor noted.

"Now he's got what he needs," Vance concluded. "I'm sure Donald Trump Jr. is at the top of his list. There has been public reporting that indicates he may have contradicted himself. But there's no telling how deep into this list he could be looking."
