House Democratic leaders on Monday demanded that freshman Rep. Ilhan Omar, D-Minn., apologize for anti-Semitic remarks and tweets, but Republicans are going further by saying they should strip Omar of a key committee assignment.

“Congresswoman Omar’s use of anti-Semitic tropes and prejudicial accusations about Israel’s supporters is deeply offensive,” House Speaker Nancy Pelosi, D-Calif., Majority Leader Steny Hoyer, D-Md., and other caucus leaders, said in a statement. “We condemn these remarks and we call upon Congresswoman Omar to immediately apologize for these hurtful comments.”
