Warren pivoted to Trump during a speech at the University of Massachusetts Amherst, offering suggestions for specific causes graduates could get more involved in.

"I'm trying to keep this apolitical but I can't help myself ... the principle that no one, no one in this country is above the law and we need a Justice Department, not an obstruction of justice department," Warren said.

Fallout over Comey's firing is the latest controversy swirling around the Trump administration, which Democrats have criticized for months over a string of issues including the president's refusal to place his assets in a blind trust or release his tax returns.

Warren on Friday didn't hold back from jabbing other members of Trump's team, mocking senior White House adviser Kellyanne Conway for the phrase "alternative facts."

"Go online and read the facts, not the alternative facts the real facts. I have to say I had never thought we would need a modifier for facts," Warren said.

The president's senior advisor injected the phrase into the national vocabulary after using it in an NBC interview to defend White House press secretary Sean Spicer's claim that Trump had the "largest audience to ever witness an inauguration, period."

The Democratic senator also knocked Trump while referencing the "Elizabeth Warren commencement speech drinking game," quipping that "fireball is a nickname Donald Trump uses on Twitter, not a beverage to be consumed by distinguished college graduates."

Noting her recommendation that graduates study policy wouldn't make her "Ms. Popularity," she added: "I think as long as Mitch McConnell is running the Senate that's out of reach for me."

McConnell rebuked Warren on the Senate floor earlier this year for criticizing Sessions, who was still a senator at the time. McConnell, justifying the move, said Warren had been warned for breaking the Senate rules, adding, "nevertheless, she persisted."
