She also shared a missive in which someone stated: "Criticism of Israel isn't anti-semitism, just like criticism of a Muslim majority state isn't Islamophobia, by default". In his tweet, Greenwald slammed House Minority Leader Kevin McCarthy (R-Calif.) for threatening to take action over Omar's criticism of Israel.
Max Rose, who won a tight race in NY, said the Democratic Party and the USA should be a place where "we celebrate the diversity of our people".
Omar's Sunday night tweets drew immediate criticism from lawmakers in both parties. "There is absolutely no place for this rhetoric in Congress - or anywhere", Gottheimer tweeted. Rep. Omar failed that test of leadership with these comments.
"We condemn these remarks and we call upon Congresswoman Omar to immediately apologize for these hurtful comments".
Deutch, who has emerged as a leading Democratic voice against anti-Semitism, also said the tweets reflected "anti-Semitic tropes".
Omar is one of two Muslim-American women who were elected to Congress in last year's midterms, along with Rashida Tlaib of MI.
"The leaders" statement came in the hours after a pair of powerful House chairman rebuked Omar for the remarks.
McCarthy directly compared their comments, which Republicans have labeled anti-Semitic, to the recent comments by Rep. Steve King of Iowa when he told The New York Times, "White nationalist, white supremacist, Western civilization - how did that language become offensive?"
The Minnesota lawmaker has previously been accused of anti-Semitism.
Others pointed out that numerous Republicans lashing out at Omar had promulgated anti-Semitic conspiracy theories in the past.
"She's talking about the influence of Israel and this immediately gets twisted into antisemitism", one man wrote in comments retweeted by Omar.
"We must speak out when any Member-Democrat or Republican-uses harmful tropes and stereotypes, levels accusations of dual loyalty, or makes reckless statements like those yesterday", the representatives wrote.
In response to Ms Omar, Aipac tweeted: "Our bipartisan efforts are reflective of American values and interests". She was referring to the American Israel Public Affairs Committee and the National Rifle Association.
Omar has been openly critical of the Israeli government over its treatment of Palestinians and is part of a movement calling to cut economic ties with Israel over Israeli occupation of the West Bank.
Omar has expressed regret for tweeting in 2012: "Israel has hypnotized the world, may Allah awaken the people and help them see the evil doings of Israel".
Republicans and Democrats alike said the tweets stoked anti-Semitic tropes about Jews and money. "Her words are deeply hurtful and offensive".
She did respond to a tweet from Clinton, saying she'd be "happy to talk". She suggested her comments were being weaponized by the GOP: "We must call out smears from the GOP and their allies". I mean, look, it's not up to us to police what people say on Twitter, you know, with respect to that.
