President Donald Trump suggested Thursday that Sen. Elizabeth Warren (D-Mass.) has a drug use problem amid their ongoing rift over his policies.

While answering questions in the Oval Office during the 90th anniversary celebration of the Social Security Act, Trump railed at the senator.

“Elizabeth Warren said she was an Indian. We call her Pocahontas. She’s a liar. She lied her whole career,” he said. “Based on the fact that she was an Indian, she was able to get into certain colleges, get certain jobs, get into certain universities to work there. And she’s a liar and a mean person.”

Warren released the results of a DNA test in October 2018 that showed she has distant Native American ancestry dating back six to 10 generations. Trump had challenged her to take that test months before.

Elsewhere, while speaking with reporters Thursday, the POTUS went on to take shots at Warren for supporting democratic socialist mayoral candidate Zohran Mamdani of New York City.
