Rep. Ilhan Omar (D-Minn.) fired back at Sen. Ted Cruz (R-Texas) on Sunday after he criticized her for what he called “repeated anti-Israel slurs.”

“A white nationalist literally terrorized a synagogue during Passover yesterday and you have yet to say anything,” the Minnesota lawmaker tweeted. “Shame on you.”

Cruz mentioned Omar in a tweet earlier Sunday when discussing a cartoon that was pulled from The New York Times after being widely panned as anti-Semitic.

{mosads}”The anti-Semitic Left—whether @IlhanMN repeated anti-Israel slurs or @nytimes apologizing for Hamas terrorists (eg, on 3/14/18) & running racist cartoons—is getting worse,” Cruz wrote. “And the House can’t even pass an anti-Semitism resolution. Responsible Dems need to say Enough is Enough.”

Omar, one of the first Muslim congresswomen, sparked criticism earlier this year for controversial comments about the American Israel Public Affairs Committee and U.S. support for Israel.

Some called her comments anti-Semitic, and the backlash prompted the passage of a House resolution condemning hate in all forms.

Omar quote-tweeted Cruz’s criticism while pointing out that he had not tweeted about Saturday’s shooting at a synagogue in California which left one person dead. 

Police have charged John Earnest, 19, with murder in connection with the shooting. A gunman opened fire on members of the Chabad of Poway Synagogue with a AR-15-style on Saturday morning.

Earnest allegedly posted a manifesto to the internet forum 8chan before the attack saying he had been inspired by the recent mosque shootings in Christchurch, New Zealand, as well as the shooting at the Tree of Life synagogue in Pittsburgh.
