Sen. Elizabeth Warren of Massachusetts put Jeff Sessions, who was just confirmed as Trump's attorney general, on notice in a series of tweets on Wednesday night.

"I’m deeply disappointed that the Senate voted to confirm Jeff Sessions as Attorney General tonight," she wrote.

"And you better believe every Senator who voted to put Jeff Sessions' radical hatred into @TheJusticeDept will hear from all of us, too," she continued, adding in another tweet: "If Jeff Sessions makes even the tiniest attempt to bring his racism, sexism & bigotry into @TheJusticeDept, he'll hear from all of us."

The tweets came after an intense confirmation process that hit a snag Tuesday night when Warren tried to recite a 1986 letter Coretta Scott King wrote that was critical of Sessions. Senators voted to force her to stop talking, invoking a rule prohibiting senators from attacking one another's conduct.

Warren seemed to refer to that incident in a final tweet Wednesday night: "Consider this MY warning: We won't be silent. We will speak out. And we WILL persist."
