A guest brought on to ask questions at a CNN town hall called out anchor Anderson Cooper for using incorrect gender pronouns during the program.

CNN host Anderson Cooper faced conservative backlash Wednesday for accidentally misgendering a town hall attendee. Cooper called on an audience member to ask a question to Sen. Bernie Sanders (I-Vt.). “I want to introduce Grace Thomas,” Cooper said. “She’s a local civil rights attorney. She’s a Democrat. Grace?”

Anderson Cooper suffered a woke faux pas after he misgendered a Democratic activist while hosting a Bernie Sanders town hall event on Wednesday.
