Trump tore into Omar early on in his rally in Greenville, N.C., a continuation of his days-long attacks against her and three other progressive minority congresswomen.
The crowd raucously booed Omar at the first mention of her name.
The president went on to accuse Omar of demeaning U.S. service members and minimizing the Sept. 11, 2001, terrorist attacks.
“She looks down with contempt on the hard-working Americans saying that ignorance is pervasive in many parts of this country,” Trump said.
The crowd then broke into a chant of “send her back” in reference to Omar, who came to the U.S. as a Somali refugee as child.

Omar responded to the chants on Twitter roughly an hour later by quoting the poem "Still I Rise" by Maya Angelou. »
