Perhaps you think she is the only person who ever said anything that could be construed as anti-Semetic, and you gladly accept it without outcry when McCarthy accuses Jews of trying to buy the midterms.

From Haaretz
At the start of the week, Democratic Congresswoman Ilhan Omar from Minnesota was back in hot water over tweets on Israeli influence in American politics. This time, according to Omar, “It’s all about the Benjamins,” the cash keeping U.S. civil servants towing the Zionist line.

It’s telling that Ilhan Omar fell so quickly back into an anti-Semitic trope after a protracted public controversy over earlier tweets on Israel hypnotizing the world. It is also grating to see Republicans like House Minority Leader Kevin McCarthy, who once suggested wealthy Jews were trying to “buy” the midterm elections, pounce at the opportunity to score partisan points. Congresswoman Omar did ultimately apologize, albeit only after censure by the House Democratic leadership.

The pretext for Congresswoman Omar’s latest contentious tweet was Kevin McCarthy’s threat of punitive action against her and Rashida Tlaib over their Israel criticism. McCarthy admonished the two Democratic representatives in a public way because it mobilizes the Republican base and inflames a wedge issue among Democrats. Contra Omar, no “Benjamins” were required to make such a move politically expedient for the GOP, even as it helps turns Israel into a partisan football.

Of course you could read the whole article, it's far more interesting than just those bits.
