WATCH: Senate Judiciary Dem threatens Huckabee Sanders with indictment over Comey intimidation

Last week, White House spokeswoman Sarah Huckabee Sanders leveled three threats against fired FBI Director James Comey. Now, a ranking Democrat on the Senate Judiciary Committee has issued threats of his own.

The three "torpedoes" Huckabee Sanders "shot at James Comey," Sen. Sheldon Whitehouse (D-RI) said on MSNBC's Hardball, have "opened up a new avenue in the case for [Special Counsel Robert] Mueller."

Citing an obstruction of justice statute, Whitehouse said that her threats from the press secretary podium could be considered a means to influence grand juries in Mueller's probe.

"So the question of Sarah Huckabee Sanders is who asked you to do that, who told you to do that?" Whitehouse continued.  "If the motivation was to poison the reputation of James Comey with the grand jurors, you have another indictment."

The Trump White House, the Rhode Island senator continued, seems to have a knack for baiting Mueller.

"I don't know why this White House hasn't stopped this stuff," he concluded, "but it really looks like every time they turn around, they're sending up another invitation to Mueller to run this down and see if you can add a count."
