Trump on Friday tweeted a video including images of Sept. 11 and comments Omar made regarding the attack and the safety of Muslims in its aftermath. The video featured footage of the burning World Trade Center and was denounced by many Democrats as Islamophobic and as endangering Omar's life. 

Omar said during a speech last month at the Council on American-Islamic Relations (CAIR) that CAIR was founded because "some people did something" and Muslims "were starting to lose access to our civil liberties."

CAIR was founded in 1994, but Omar's office has said she meant to say that the organization grew following the 9/11 attacks.
