Sen. Martha McSally’s campaign has begun selling “liberal hack” T-shirts a day after she used the term to dismiss a question from a CNN reporter.

The Arizona Republican, who is facing a tough election battle against retired astronaut and U.S. Navy Capt. Mark Kelly, began selling the shirts from the domain www.liberalhack.com, a website that redirects to a fundraising page asking for at least $35 to receive the shirt.
