Ohio Republican Senate candidate Jane Timken blasted the NCAA and Democrats over transgender swimmer Lia Thomas competing in women’s sports in a new campaign ad released on Monday.

The 30-second ad called “Compete” shows Timken highlighting her background as a former female college athlete, blaming rules by the NCAA for allowing biological males to compete in women’s sports on the failed leadership of President Joe Biden and the Democratic Party.

“As a mom and former college athlete, I know how important women’s sports are. They teach our girls to be winners,” Timken said in the video.
