Campaign finance records show that McCready refunded Omar's $2,000 contribution on March 30. Omar donated the money on Nov. 6.
A representative said McCready gave back the money because he believes there is no place for divisiveness in politics, and he did not feel it is was fitting to accept the donation.
McCready wrote on Twitter on April 17 that he asked for the refund weeks ago and that he disagrees with any anti-Semitic remarks.
He then said, "I condemn, in the strongest terms, the hateful rhetoric against her, the Muslim community, and people of color. Too many have been hurt by our broken politics. We must end hate speech against all people and groups."
President Donald Trump responded to Omar's description of the Sept. 11, 2001, terror attacks, in a Tweet on April 12.
In his post, Trump wrote, "WE WILL NEVER FORGET!" accompanied by a video compilation of footage from the terrorist attacks. The video ends with the text, "September 11, 2001, We Remember."
The president's post was in response to Omar's description of the attacks, who called it "some people did something." Her comments were made as part of a speech last month at a Council on American-Islamic Relations (CAIR) fundraiser, during which she said the radical Muslim group was founded after the terror attacks.
“CAIR was founded after 9/11 because they recognized that some people did something and that all of us were starting to lose access to our civil liberties,” Omar said.
