Sen. Elizabeth Warren, D-Mass., said Friday that President Trump’s tweets accusing the Democratic National Committee of rigging the Democratic primaries in favor of Hillary Clinton won’t “keep your people out of jail.”

Warren fired back at Trump on Twitter after the president called her “Pocahontas” and said the Justice Department and FBI should be investigating claims from former interim DNC Chairwoman Donna Brazile. In a new book, Brazile said Clinton’s campaign took control of the party’s finances and operations to ensure she clinched the nomination.

“I understand your desperation to change the subject, @realDonaldTrump. Your campaign mgr was just indicted for conspiracy against the US,” Warren tweeted.

The Massachusetts senator was referencing former Trump campaign chairman Paul Manafort, who, along with former business associate Rick Gates, was indicted by a federal grand jury on 12 counts on Monday.

“You might think your tweets are cute, @realDonaldTrump, but they won’t stop Mueller’s investigation or keep your people out of jail,” Warren said in subsequent tweets. “The DNC shouldn’t play favorites. But that’s a whole lot different from illegally conspiring with Russia. The FBI knows the difference.”

“Slurs, lies & trash talk won’t stop the FBI from doing its job. This isn’t a dictatorship. It’s our democracy. And it’s stronger than you,” she continued.

Special counsel Robert Mueller is investigating ties between Trump campaign officials and Russia, and the charges against Manafort and Gates were the first filed in his Russia probe.

But Trump has long maintained the Justice Department should be investigating the DNC and Clinton instead.

Speaking to reporters Friday morning, the president said he was “disappointed” in the Department of Justice and questioned on Twitter why it and the FBI weren’t “looking into all of the dishonesty going on with Crooked Hillary & the Dems.”
