US President Donald Trump blasted Democrats as "anti-Israel" and "anti-Jewish" Friday after they passed a congressional measure opposing hate speech in general instead of specifically condemning alleged anti-Semitic comments by a Muslim congresswoman.
His remarks follow days of tense debates in Congress addressing sensitive questions about national allegiance, discriminatory tropes aimed at Jews, and accusations of show votes that failed to call out a member for controversial comments.
"I thought yesterday's vote by the House was disgraceful," President Trump said at the White House.
The resolution was originally intended to deliver a direct rebuke of anti-Semitism following comments by a Muslim Democratic congresswoman, Ilhan Omar, that were deemed anti-Semitic and offensive by many colleagues.
But after blowback from progressives, it was revised to broadly condemn discrimination against Muslims and other minorities as well.
Mr Trump seized on the shift, injecting a new angle of attack as he readies a 2020 re-election bid and fellow Republicans seek to claw back ground they lost in the House in last year's mid-terms.
"The Democrats have become an anti-Israel party, they've become an anti-Jewish party," he said.
The issue has caused a deep rift. Some Democrats wanted to include language condemning other forms of bigotry, and expressed concerns about singling out Ms Omar.
The resolution, which made no mention of Ms Omar, ultimately passed 407 to 23. Republicans who voted against it complained it had been watered down.
The debate made clear that Democrats' growing diversity in Congress -- in ethnicity, religion, gender, age and ideology -- has created new challenges for the party.
Among those is policy about Israel. Ms Omar, a Somali refugee who resettled in Minnesota, had sparked fiery debate with her repeated criticisms of Israel and how a powerful pro-Israel lobby in Washington exerts influence on US politicians.
"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," Ms Omar tweeted. "Our nation is having a difficult conversation."
But Democrats insisted President Trump was out of bounds to suggest their party was anti-Jewish.
"Mr President, you have redefined chutzpah," said Senate Minority Leader Chuck Schumer, who like Mr Trump is from New York.
"As illustrated by history and yesterday's overwhelming vote to condemn anti-Semitism, there is strong support for Israel and the Jewish faith among Democrats," congresswoman Elaine Luria, a military veteran who is Jewish, told AFP.
The debate comes amid a rise in anti-Semitic incidents across the United States. The Anti-Defamation League reported a 58 percent increase in such incidents between 2016 and 2017.
In October a gunman killed 11 worshippers at a Pittsburgh synagogue, the deadliest attack ever on Jews in America.
President Trump proclaims himself as Israel's closest ally, having moved the US embassy from Tel Aviv to Jerusalem, and forged a close alliance with Prime Minister Benjamin Netanyahu.
But he and other Republicans have also courted controversy with the Jewish community, and have been accused of trafficking in age-old tropes about money that anti-Semites have used to attack Jews for centuries.
Speaking to the Republican Jewish Coalition in 2015 during his presidential campaign, Mr Trump said "you're not going to support me because I don't want your money."
"But that's okay," he went on. "You want to control your own politician."
The President drew outrage in 2016 with a tweet showing his rival Hillary Clinton and a Star of David with the word "corrupt" superimposed over stacks of $100 bills.
And his closing 2016 campaign ad contained alarming messaging, with images of prominent financial figures George Soros and Janet Yellen, both Jewish, as Trump speaks of "those who control the levers of power in Washington."
As President, Mr Trump sparked a firestorm by saying there were "very fine people on both sides" at a 2017 white nationalist rally in Charlottesville, where demonstrators chanted "Jews will not replace us."
Of the 535 members of the US House and Senate, 35 are Jewish, including just two Republicans, according to the non-partisan American-Israeli Cooperative Enterprise.
Pew Research Center says that among Jewish voters in the 2018 midterms, 79 percent supported Democratic candidates.
