Several Pennsylvania lawmakers have now joined a growing outcry against a controversial University of Pennsylvania professor who recently wrote that the U.S. is "better off with fewer Asians and less Asian immigration."

State Senator Anthony H. Williams condemned the comments from Amy Wax on Thursday and called on the university to stop allowing the professor to "hide behind the veil of tenure to spew her hateful speech," The Philadelphia Inquirer reported.

"We stand for tenure," Williams was quoted by the paper. "We do not stand for hate speech.

Wax was interviewed on economist Glenn Loury's podcast in December, where she described the immigration of "Asian elites" into the U.S. as problematic, the Inquirer reported. She also wrote a letter that was published on Loury's website in response to one podcast listener who wrote in after her interview was released to say that her immigration views "disturbed me."
