CNN anchor Chris Cuomo apologized on social media for jokingly agreeing with 2020 presidential hopeful Kamala Harris that their preferred pronouns are "she, her, and hers."

Cuomo tweeted an apology Thursday night, following CNN's LGBT town hall, during which he moderated the half-hour town hall for the California senator.

PLEASE READ: When Sen. Harris said her pronouns were she her and her's, I said mine too. I should not have. I apologize. I am an ally of the LGBTQ community, and I am sorry because I am committed to helping us achieve equality. Thank you for watching our townhall. — Christopher C. Cuomo (@ChrisCuomo) October 11, 2019

"PLEASE READ: When Sen. Harris said her pronouns were she her and her's, I said mine too," the anchor stated on Twitter. "I should not have. I apologize. I am an ally of the LGBTQ community, and I am sorry because I am committed to helping us achieve equality. Thank you for watching our townhall."

Cuomo jokingly said, "Mine too," when Harris shared that her pronouns were "she, her, and hers" as she walked onstage.

"All right," Harris said, before moving on.

The California senator was one of nine presidential candidates to appear at CNN's LGBT town hall event.
