Conservative radio host Rush Limbaugh said Monday no one will “push back” against freshman Rep. Alexandria Ocasio-Cortez, D-N.Y., which he argued is stunting the 29-year-old’s growth as a politician.

“She routinely demonstrates her ignorance,” Limbaugh said on his radio program. “I’m trying to be nice here. I’m not calling it stupidity, although — but I’m not. I’m gonna chalk it up to ignorance. She has nobody that pushes back on her. There’s not a soul anywhere that will push back on her. Therefore, there’s no pressure for this woman to mature. There is no pressure for her to grow up.”
