Later, Twitter user Batya Ungar-Sargon, an opinion editor for the Forward, wrote, "Would love to know who @IlhanMN thinks is paying American politicians to be pro-Israel, though I think I can guess". She has called the efforts to paint her as an anti-Semite a smear.
A new Democratic congresswoman is facing a firestorm of criticism for suggesting United States politicians only support Israel because of lobby money.
The freshman Democrat was appointed to the Foreign Affairs Committee in January.
But not every lawmaker smacked Omar for her tweets. "Congresswoman Omar's comments are deeply hurtful to Jews, including myself", he wrote. House Minority Leader Kevin McCarthy (R-CA) even equated some of Omar's comments to those of Rep. Steve King (R-IA) who was formally renounced by Congress over comments he made to the New York Times questioning when language like white supremacist became offensive.
Omar's tweet implied that McCarthy was only calling for punishment against her and fellow Democratic House member Rashida Tlaib because of financial support from the pro-Israel lobby.
Critics of the tweet included many Republican members of Congress, former first daughter Chelsea Clinton and former ambassador to Israel under President Barack Obama Daniel B. Shapiro. "Implying that Americans support Israel because of money alone is offensive enough".
Omar, who supports the anti-Israel movement called BDS, for "boycott, divestment and sanctions", has persistently fought accusations of anti-Semitism by maintaining that her condemnation of the Israeli government for its treatment of Palestinians does not equate to condemnation of Jewish people.
"Our bipartisan efforts are reflective of American values and interests", AIPAC tweeted Sunday.
Neither Omar's office in Minnesota nor in Washington immediately responded for comment to Newsweek when asked about the tweet, which appears to invoke an old anti-Semitic stereotype portraying Jews as rich, and using their wealth to orchestrate political affairs.
The spat spurred a conversation about the political influence of AIPAC, which spends millions lobbying on legislation each year.
"OF COURSE it's possible to critique AIPAC et al in a non-anti-Semitic way", Ungar-Sargon wrote.
Soon after, Omar responded to Clinton, saying, "Chelsea - I would be happy to talk".
"We should expect all elected officials, regardless of party, and all public figures to not traffic in anti-Semitism", Clinton said. "The Congresswoman's statements do not live up to that do not live up to that cherished ideal", Rose said.
