House Democratic leaders put off an increasingly contentious dispute over an anti-Semitism resolution that indirectly rebukes one of their own members, Ilhan Omar, a high-profile freshman from Minnesota.

The measure, originally set for a vote on Wednesday, is being sent to the Foreign Affairs Committee and timing for a vote hasnโ€™t been determined, House Speaker Nancy Pelosi told reporters.

Heated objections from some factions of Democratic lawmakers delayed a vote on the measure that was set for Wednesday, prolonging the internal strife as leaders sought to add language condemning other types of bigotry.

Itโ€™s also soaked up attention and time as Pelosi is trying to move on the Democratsโ€™ legislative agenda, including a long-promised package on ethics and ballot access.

Emerging from a closed-door meeting, some Democrats โ€” including progressives and members of the Congressional Black Caucus โ€” defended Omar and said they feared for her safety, while others spoke about the harm of historic anti-Semitic tropes and the need to take an official position.

Karen Bass, the head of the Congressional Black Caucus, said her group will meet Wednesday to discuss their position on the resolution. She said she supports Omar and expressed frustration with the way the Democratic response has been handled.

The dispute creates a problem for Pelosi, who is trying to maintain unity among Democrats, including Omar and other high-profile freshmen, as veteran lawmakers are demanding a clear resolution denouncing Omarโ€™s remarks.

President Donald Trump attacked Democrats over failing to take up the measure. โ€œIt is shameful that House Democrats wonโ€™t take a stronger stand against Anti-Semitism in their conference,โ€ Trump tweeted. โ€œAnti-Semitism has fueled atrocities throughout history and itโ€™s inconceivable they will not act to condemn it!โ€

Omarโ€™s name doesnโ€™t appear in the current draft of the resolution but it denounces anti-Semitism by describing tropes similar to some of those she has invoked. Omar, 36, apologized for previous comments derided as anti-Semitic, pledging to โ€œcombat hate of all kinds,โ€ and she has defended her right to question U.S. foreign policy.

Reworking the language of the resolution to be a broader condemnation of prejudice so far has done little to calm her supporters among progressives, including fellow freshman Alexandria Ocasio-Cortez of New York, who said there are far worse examples of offensive behavior and statements in Congress. In some cases, Omarโ€™s supporters defended her underlying point that historic ties between the U.S. and Israel should be re-examined.

Pelosi said she met personally with Omar regarding her comments and on Wednesday said she still hasnโ€™t seen the text of the resolution.

Rep. Eliot Engel, chairman of the Foreign Affairs Committee on which Omar sits, said there is no discussion of removing her from the committee, as some Republicans have demanded. Engel of New York, one of the first Democrats to publicly condemn her comments last week referring to an expectation of allegiance to Israel, said he took personal offense to her words and that an official rebuke is โ€œthe right thing to do.โ€

โ€œI donโ€™t want to do anything to jeopardize the talks going on right now and wording being worked out, and I donโ€™t really want to throw a monkey wrench into it,โ€ said Engel, who is Jewish. โ€œBut I want to tell you we have to have a strong statement condemning anti-Semitism and I believe we will.โ€

Ocasio-Cortez, a 29-year-old champion of progressive causes with a large social media following, called the resolution a โ€œnuclear optionโ€ on Twitter and urged Democratic leaders to use the moment for a lesson in inclusion, rather than censure.

โ€œI believe that Ilhan, in her statement a few weeks ago, has demonstrated a willingness to listen+work w/impacted communities,โ€ Ocasio-Cortez said in a tweet. โ€œIf we called resolutions on sexist statements, a good chunk of Congress would be gone. To jump to the nuclear option every time leaves no room for corrective action.โ€

Ocasio-Cortez and Omar, together with Ayanna Pressley of Massachusetts and Rashida Tlaib of Michigan, have called themselves a โ€œsquadโ€ in social media posts and have publicly come to each otherโ€™s defense.

Tlaib, who was on stage with Omar at an event last week when she made the comment about โ€œallegiance to a foreign countryโ€ thatโ€™s been criticized, later compared Omar to โ€œcivil rights icons before us who spoke out about oppressive policies.โ€

The resolution would be the second anti-Semitism measure to pass under the Democratic majority, although the first one was presented by Republicans in a surprise procedural vote on a resolution regarding Yemen โ€” the same week Omar tweeted rap lyrics to suggest pro-Israel politicians were motivated by money. Omar apologized for those tweets, but defended her original question about the influence of The American Israel Public Affairs Committee.

Republicans have also been accused of trafficking in anti-Semitic tropes. Jim Jordan of Ohio, the ranking Republican on the House Oversight Committee, on Sunday tweeted that the Democratic chairman of that committee, Jerrold Nadler, who is Jewish, was siding with billionaire and impeachment-advocate Tom Steyer, whose father is Jewish.

His spelling of โ€œ$teyerโ€ was criticized for suggesting a connection between Jewish individuals and money. Nadler later tweeted that Jordanโ€™s comment โ€œcounts as both inane AND anti-Semitic.โ€

Omar herself has been the target of prejudice and threats of violence. Last week, a display from West Virginia Republicans linked Omar, who is Muslim and wears a hijab, to the September 11 terror attacks. She has received death threats, and she says her experience coming to the United States from a refugee camp in Kenya has helped her understand persecution and weather her current controversy.

โ€œI know what it feels to be someone who is of faith that is vilified,โ€ Omar said in the same comments that inspired this resolution. โ€œI know what it means to be someone whose ethnicity is vilified.โ€
