“Ilhan Omar is a leader with strength and courage. She won’t back down to Trump’s racism and hate, and neither will we. The disgusting and dangerous attacks against her must end,” Sen. Bernie Sanders (I-Vt.) tweeted.

Sen. Elizabeth Warren (D-Mass.) also accused the president of inciting violence against Omar and other American Muslims while calling on lawmakers to condemn his rhetoric.

“The President is inciting violence against a sitting Congresswoman—and an entire group of Americans based on their religion. It’s disgusting. It’s shameful. And any elected leader who refuses to condemn it shares responsibility for it,” she tweeted Friday evening.
