President Joe Biden’s nominee for comptroller of the currency, Saule Omarova, withdrew her name from Senate consideration for the post on Tuesday.

Omarova’s withdrawal came after concerns from Republican senators about the Cornell University professor’s writings as a legal scholar, as well as her background of being raised in the former Soviet Union.

“I don’t know whether to call you professor or comrade,” Sen. John Kennedy, R-La., said last month at her Banking Committee confirmation hearing, in a quip that was criticized by Democrats.

Another Republican, Sen. Pat Toomey of Pennsylvania, that day said, “My concern with Professor Omarova is her long history of promoting ideas that she herself describes as ‘radical.’ ”

“I agree that they are radical. But I’d also describe them as socialist,” Toomey said.
