Videos shared with Fox News Digital showed demonstrators yelling, "Riley Gaines, go away" and "Can’t swim, Riley," among other insults. Gaines is a former University of Kentucky swimmer and received All-American honors 12-times.

Gaines took to X, the company formerly known as Twitter, and shared a video of what appeared to be an organized rally in Milwaukee.

"For this reason and this reason only, I'll be quitting my activism of fighting to protecting women's sports and single-sex spaces. 

"Things like this have become FAR too intimidating and happen way too often. This was the final straw..." Gaines wrote in the post accompanied by the video.

About 15 minutes after Riley shared the video of the demonstrators, she provided another updated.

"Sike! If you really think this does anything other than make me chuckle and resort to prayer for them, you would be wrong. Trans genocide does not exist. I'm advocating for the bare minimum: privacy, safety, and fairness for women. & I CAN swim," Riley wrote in the social media post accompanied by a selfie.

Earlier this month, Gaines targeted by "hostile" demonstrators that gathered in Texas in opposition of the "Save Women’s Sports Act."

Gaines was joined by Texas Governor Greg Abbott and others at the Texas Women’s Hall of Fame at Texas Woman’s University in Denton for a ceremonial signing of the bill, which had been signed into law in June.

Attendees said demonstrators at the scene threw items and spat at those who gathered in support of the legislation.
