President Donald Trump on Monday said freshman Democratic congresswoman Ilhan Omar "should be ashamed of herself" over tweets suggesting that a powerful pro-Israel interest group paid members of Congress to support Israel.

"I think she should be ashamed of herself," Trump told reporters on Air Force One while flying to a campaign rally in El Paso, Texas, according to The Hill. "I think it was a terrible statement, and I don't think her apology was adequate."

The Minnesota congresswoman "unequivocally" apologized earlier Monday after House Speaker Nancy Pelosi and other Democrats rebuked her.

Omar said she had no intention of offending anyone and thanked her colleagues for educating her on anti-Semitic tropes.
