Rep. Joaquin Castro (D-Texas) didn’t pull any punches against Fox News host Laura Ingraham when he called her a white supremacist on Wednesday.

Castro tweeted about living conditions at the Clint Border Patrol Station in Texas, where the U.S. government has imprisoned migrant children who have made the perilous journey to the U.S.-Mexico border. Castro visited the facility on Tuesday, NPR reported.

Ingraham —a virulent racist who has cozied up to white nationalists and continued to downplay the inhumanity of separating migrant children from their families and placing them in cages — chimed in, comparing the conditions for children in detention to those of U.S. soldiers fighting in Iraq.

“Similar to Army facilies in Iraq I was (and used) visiting Camp Victory & Balad. Think @JoaquinCastrotx needs to spend more time overseas w/ our troops bef he calls this inhumane,” she tweeted.
