“Donald Trump is hiding something and we know where he’s hiding it. Not in a safe. Not in a vault. Nope. He’s hiding it in his taxes,” Warren said in a MoveOn.org video Friday.

“[It’s] not just an ethical problem, but who exercises influence? Who really calls the shots over the man who now sits in the White House? Donald, the time for hiding is over.”

Warren voiced support for global rallies planned for Saturday aimed at forcing the release of Trump’s tax returns.

“People will be marching to tell Donald Trump they want to know who he really is working for and for Congress to force Donald Trump to release his taxes,” she said.

"The American people definitely didn’t elect Wall Street or Saudi Arabia or Russia to run our country."

Tens of thousands of people are expected to attend rallies Saturday. The central event is taking place in Washington, and similar rallies are set for 150 other cities in the U.S. and abroad.

Saturday is April 15, the traditional deadline for people to file their federal tax returns. Because it falls on a Saturday, and Monday is a local Washington holiday called Emancipation Day, the IRS's tax deadline was moved back to Tuesday, April 18, this year.

Trump has refused to release his tax documents, claiming he can't do so because he's under audit. The IRS has said there's no reason an individual under audit couldn't release their tax returns.
