Rep. Maxine Waters, D-Calif., vowed on Saturday not to rest until she sees President Trump impeached.

Waters used Tax Day as a platform to bring attention to Trump's refusal to release his tax returns. Speaking to attendees at the Washington, D.C., Tax Day rally, Waters announced that she doesn't trust Trump.

"I will fight every day until he is impeached," she said to cheers.

This year's Tax Day inspired more than 150 marches nationwide to call on President Trump to release his tax returns, including one near Trump's Mar-a-Lago resort in Palm Springs, Fla., where he is staying this Easter weekend.

Waters, who has become left-wing favorite in recent weeks for her apologetically harsh rhetoric and spat with Fox News' Bill O'Reilly, accuses the president of wasting taxpayers money and enriching himself at his resort.
