Freshman Democratic Congresswoman Ilhan Omar condemned U.S. President Donald Trump’s "vile attacks" and "demented views" in a rally of support on Capitol Hill Tuesday.

Capitol Hill rally backs freshman Rep. Ilhan Omar

"We are collectively saying your vile attacks, your demented views are not welcome here," the Minnesota Democrat said in her first public remark since Trump attacked her for recent comments on 9/11 and reports of death threats against her.

Omar was joined Tuesday by fellow progressive freshmen Democratic Reps. Rashida Tlaib of Michigan and Ayanna Pressley of Massachusetts - as well as activist Angela Davis.

"This is not going to be the country of the xenophobics. This is not going to be the country of the white people. This is not going to be the country of the few. This is going to be the country of the many."

"At this moment, the occupant of the White House ... and his allies are doing everything that they can to distance themselves and misinform the public from the monsters that they created that is terrorizing the Jewish community and the Muslim community," Omar said. "Because when we are talking about anti-Semitism we must also talk about Islamophobia. It is two sides to the same coin of bigotry."

"Just this week, when we've had the attack in California on a synagogue, it is the same person who is accused of attempting to bomb a mosque. So I can't ever speak of Islamophobia and fight for Muslims if I am not willing to fight against anti-Semitism," Omar continued. "We collectively need to make sure that we are dismantling all systems of oppression."

Trump did not wish any harm in his Twitter post criticizing Democratic congresswoman Ilhan Omar's comments on the 9/11 attacks, White House spokeswoman Sarah Sanders said in mid-April.

"Certainly the president is wishing no ill will, certainly not violence towards anyone," Sanders told ABC News' "This Week" show. "But the president is absolutely and should be calling out the congresswoman for her, not only one-time, but history of anti-Semitic comments," she said.

Lawmakers from Trump's Republican Party have accused Omar of minimizing the Sept. 11, 2001, hijacked plane attacks by al Qaeda on the United States that killed almost 3,000 people, while critics of the president say he took Omar's words out of context in order to stoke anti-Muslim sentiment.

A day before Sander’s remark, Trump tweeted a video suggesting that Omar, a U.S. representative from Minnesota, had been dismissive of the 9/11 attacks that destroyed New York's World Trade Center and struck the Pentagon outside Washington. The video spliced news footage of 9/11 with a clip from a speech Omar gave last month in which she described the attack as "some people did something."
