This statement attracted more hateful comments towards the Congresswoman after Trump tweeted it with the caption "We will never forget!" and added an edited video of the 9/11 attacks.
Pelosi said in her statement that "following the President's tweet, I spoke with the Sergeant-at-Arms to ensure that Capitol Police are conducting a security assessment to safeguard Congresswoman Omar, her family and her staff". She wasn't minimizing the tragedy; she was suggesting that what some Muslims did threatened all Muslim Americans' civil liberties. She called on Trump to discourage such behaviour.
Lawmakers from Trump's Republican Party have accused Omar of minimizing the September 11 attacks, while critics of the president say he took Omar's words out of context in order to stoke anti-Muslim sentiment. 'President Trump must take down his disrespectful and risky video'.
The video tweeted by Mr Trump spliced news footage of 9/11 with a clip from a speech Ms Omar gave last month in which she said "some people did something" in reference to the attacks.
It can not be pleasant for Omar's colleagues to have to wonder and worry what that next remark will be-knowing that Donald Trump and his Twitter feed will be waiting to blame all Democrats for the provocations of one.
Critics accuse Omar of offering a flippant description of the assailants behind the attack that killed almost 3,000 people.
She was discussing civil rights for Muslim Americans in the wake of the 9/11 attacks. "The disgusting and risky attacks against her must end".
Warren called the incident "disgusting" and "shameful, while Sanders said Omar "won't back down to Trump's racism and hate, and neither will we".
"Was Bush downplaying the terrorist attack?" It would be no more appropriate to accuse Trump of inciting violence against Omar than it would be to hold the far left at fault for the 2017 congressional baseball shooting, which was perpetrated by a Sanders supporter who had appropriated some views of the Republicans-are-the-real-Taliban variety.
"I just happen to embody all of those identities", Omar said on the CBS show last week.
The president will not stop. Some also noted their past disagreements with her. As a refugee in America, a teenage Omar arrived in the big city of Minneapolis, where she rose to become a Democratic member of the state assembly.
Referring to her previous controversial comments, in which Ms Omar questioned U.S. support for Israel, Ms Sanders added: "It's absolutely abhorrent the comments that she continues to make and has made and they look the other way". "We can no longer ignore that they are being encouraged by the occupant of the highest office in the land". Trump's comment to the Republican Jewish Coalition came a day later. "It has to stop", she said. In doing so, and by refusing to pledge allegiance to Israel, she's faced vicious smears calling her antisemitic (including from Trump).
Rep. Jerry Nadler, a New York Democrat whose constituents include Manhattan's financial district, which was targeted on September 11, 2001, said he had no issues with Omar's characterization of the attack. Even many of those attempting to show her support are still mischaracterizing what she said, either because they didn't watch the speech, or because they're afraid of taking a stance that might alienate those who didn't.
