House Speaker Nancy Pelosi said Sunday that she has asked the U.S. Capitol Police to increase its protection of Rep. Ilhan Omar after President Trump tweeted a video of the Minnesota Democrat spliced with footage of the burning twin towers.

“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,” Pelosi (D-Calif.) said in a statement. “They will continue to monitor and address the threats she faces.”

Typically, only members of congressional leadership have designated Capitol Police security details.

Trump’s tweet on Friday prompted accusations from some Democrats that he was engaging in Islamophobia, inciting violence and politicizing one of America’s gravest tragedies.

The tweet came after conservative media outlets last week circulated a snippet of a recent speech made by the freshman Democrat, one of the first two Muslim women elected to Congress.

In the speech, Omar had used the phrase “some people did something” in reference to the Sept. 11, 2001, terrorist attacks, language that conservatives argued played down the significance of the event.

Pelosi had earlier come under criticism from some Democrats, including Rep. Rashida Tlaib (Mich.), for a statement in which she condemned the video Trump shared but made no mention of Omar.

On Sunday, in addition to mentioning Omar, Pelosi called on Trump to “take down his disrespectful and dangerous video.”

“The President’s words weigh a ton, and his hateful and inflammatory rhetoric creates real danger,” the speaker said.

Last week, a man in New York was arrested and charged with threatening to kill Omar, whom he had described as a “terrorist.” The next day, Trump criticized the Minnesota Democrat during a speech to a conservative Jewish group, declaring that Omar “doesn’t like Israel.”
