During a speech on Monday, Rep. David Stringer (R) said “there aren’t enough white kids to go around,” according to The Associated Press.

“I am calling on him to resign immediately,” Arizona GOP Chairman Jonathan Lines said in a statement following the comments. “These words have no place in our party, or in our state.”

The development comes one day after a clip of Stringer’s speech was circulated across news outlets and social media.

“Sixty percent of public school children in the state of Arizona today are minorities. That complicates racial integration because there aren’t enough white kids to go around,” Stringer said in the speech.
