ESPN and its lead NBA reporter Adrian Wojnarowski are apologizing after he replied with an expletive quip to U.S. Senator Josh Hawley of Missouri following a news release.

Hawley sent out a release publicly criticizing the NBA and Commissioner Adam Silver for allowing players to promote social justice on their jerseys this season. Wojnarowski replied with a two-word response that the senator’s office posted on Twitter.

ESPN said the statement was “completely unacceptable.” Wojnarowski wrote on Twitter that he was disrespectful and made a regrettable mistake. He said he would contact the senator directly to apologize.

Hawley tweeted at ESPN to not suspend “Woj” as he is known in NBA circles.
