(JTA) — Chelsea Clinton cited the lessons of Purim to chastise a congressman who said restoring Western civilization could not be done “with somebody else’s babies.”

“Clearly the Congressman does not view all our children as, well, all our children,” Clinton, the daughter of former President Bill Clinton and Hillary Clinton, who lost the November presidential election to Donald Trump, said Sunday in a tweet quoting a tweet by Rep. Steve King, R-Iowa. “Particularly ironic & painful on Purim.”

Clinton’s husband, Marc Mezvinsky, is Jewish. Purim celebrates the triumph of Persia’s Jews over a deadly enemy, Haman. Some Jewish traditions cite its lessons as upholding diversity.

King in his tweet praised Geert Wilders, the anti-Islam Dutch lawmaker whose party is among those competing in elections this week in the Netherlands.

“Wilders understands that culture and demographics are our destiny,” he said. “We can’t restore our civilization with somebody else’s babies.”

The tweet was reviled as bigoted almost as soon as King posted it.

“This is so offensive, it’s hard to know where to start,” Jonathan Greenblatt, the Anti-Defamation League CEO, said in a tweet. “America’s greatness is the diversity of our culture, the dynamism of our demography.”

Rep. Nancy Pelosi, D-Calif., alluded to King’s closeness to Trump, and claims from Democrats that Trump’s election has spurred increased bigotry, in calling the comment “racist.”

“It’s no accident that communities across America have been threatened by emboldened racists,” she said in a statement Monday. “The GOP Leadership must stop accommodating this garbage, and condemn Congressman Steve King’s statements in the strongest and most unequivocal terms.”

In an appearance on CNN on Monday morning, King would not say whether he believed Muslims were “equals,” but defended the tweet from charges that it was racist.

“It’s the culture, not the blood,” King said. “And if you can go anywhere in the world and adopt these little babies and put them into households that were already assimilated into America, those babies will grow up as American as any other baby with as much patriotism and as much love of country as any other baby. It’s not about race.”
