Omar has come under fire for saying at a Washington bookstore forum last week that pro-Israel advocates are pushing "allegiance to a foreign country."
Staffs from the offices of Speaker Nancy Pelosi (D-Calif.), Majority Leader Steny Hoyer (D-Md.), Foreign Affairs Committee Chairman Eliot Engel (D-N.Y.) and Rep. Ted Deutch (D-Fla.) worked on the resolution over the weekend.
The senior Democratic aide said the resolution, which was first reported by Politico, was being drafted before the Anti-Defamation League sent a letter on Monday urging Democratic leaders to consider a resolution condemning Omar's remarks.
A copy of the resolution's text obtained by The Hill does not specifically cite Omar's latest comments.
It does state that "accusations of dual loyalty generally have an insidious, bigoted history," and declares that the House "acknowledges the dangerous consequences of perpetuating anti-Semitic stereotypes" and "rejects anti-Semitism as hateful expressions of intolerance that are contradictory to the values that define the people of the United States."
The resolution further notes that the history of dual loyalty accusations includes the internment of Japanese-Americans in World War II and "the post-9/11 conditions faced by Muslim-Americans in the United States, including unfounded, vicious attacks on and threats to Muslim-American members of Congress."
It won't be the first time the House has voted in recent weeks to condemn anti-Semitism in response to comments made by Omar about Israel. Omar last month apologized after suggesting that U.S. lawmakers defending Israel were motivated by money, writing on Twitter that "it's all about the Benjamins baby."
Omar's latest remarks at the bookstore event last week came while arguing that critics calling her anti-Semitic were trying to silence debate in bad faith.
"I want to talk about the political influence in this country that says it is OK for people to push for allegiance to a foreign country," Omar said.
Omar doubled down on her comments over the weekend, despite criticism from Engel and House Appropriations Committee Chairwoman Nita Lowey (D-N.Y.), both of whom are Jewish.
"I should not be expected to have allegiance/pledge support to a foreign country in order to serve my country in Congress or serve on committee," Omar tweeted.
"I am told everyday that I am anti-American if I am not pro-Israel. I find that to be problematic and I am not alone. I just happen to be willing to speak up on it and open myself to attacks."
