Alexandria Ocasio-Cortez, Bernie Sanders and Others Respond to Donald Trump's 9/11 Tweet Criticizing Ilhan Omar

A tweet published late Friday afternoon by President Donald Trump stirred up more controversy and reaction from Democrats who found the message to be offensive.

The tweet, posted by Trump at 5:35 ET, featured a video of Minnesota Rep. Ilhan Omar speaking to the Council on American-Islamic Relations (CAIR) in March. Omar's comments are followed by images of the September 11, 2001 terrorist attacks on the World Trade Center and the Pentagon.

"CAIR was founded after 9/11 because they recognized that some people did something," Omar says in the video with "some people did something" repeated multiple times as images from the attacks are played.

The tweet is currently pinned to the top of Trump's account.

The comments from Omar are part of a larger speech where the congresswoman said, "Far too long we have lived with the discomfort of being a second-class citizen, and frankly, I'm tired of it, and every single Muslim in this country should be tired of it…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."

The speech, which was posted to YouTube in its entirety this week, has stirred up controversy over Omar's comments, with some conservatives objecting to the same "some people did something" phrase repeated in the video as being dismissive of the 9/11 attacks.

Shortly after Trump posted the tweet, New York Rep. Alexandria Ocasio-Cortez called on Congress to "respond to the president's explicit attack."

"Members of Congress have a duty to respond to the President's explicit attack today. @IlhanMN's life is in danger. For our colleagues to be silent is to be complicit in the outright, dangerous targeting of a member of Congress. We must speak out. "First they came...," Ocasio-Cortez wrote.

Sens. Bernie Sanders and Elizabeth Warren, both of whom are 2020 presidential candidates, also responded to Trump's tweet.

"Ilhan Omar is a leader with strength and courage. She won't back down to Trump's racism and hate, and neither will we. The disgusting and dangerous attacks against her must end," Sanders said.

"The President is inciting violence against a sitting Congresswoman — and an entire group of Americans based on their religion. It's disgusting. It's shameful. And any elected leader who refuses to condemn it shares responsibility for it," Warren wrote on Twitter.

Washington governor Jay Islee, who is also campaigning for a 2020 presidential bid, also defended Omar in a tweet, saying, "President Trump's inflammatory and dangerous rhetoric towards Ilhan Omar is jeopardizing her safety. He is deliberately putting her and all Muslim Americans in harm's way."

"Enough is enough. No more silence, with NY Post and now Trump taking Ilhan's words out of context to incite violence toward her, it's time for more Dems to speak up. Clearly the GOP is fine with this shameful stunt, but we cannot stand by," Rep. Rashida Tlaib, another Muslim congresswoman, said.

Speaker of the House Nancy Pelosi and Senate Majority Leader Mitch McConnell have not publicly responded to the president's tweet. However, #IStandWithIlhan was trending on Twitter as of 10 p.m. ET.
