Riley Gaines became the face of fairness in women's sports, but it wasn't exactly in her plans to do so.

Gaines decided to speak out against biological males in women's sports shortly after Lia Thomas, a transgender female, took home the 2022 NCAA Division I title for the 500-yard freestyle.

But earlier that season, Gaines actually had no idea who Thomas was.

In the 2020-21 season, Gaines was ranked seventh in the country. Of course, she wanted to be at the top for her senior season the next year.

Early in the 2021-22 season, Gaines says she was on track to be there, ranking third by mere hundredths of a second. However, she had never heard of the person who was in first place "by body-lengths."

Gaines and her teammates were confused about this mystery swimmer, and she "continued to stay in the dark" until an article revealed Thomas' identity as a biological male.

Ironically, Gaines said she felt a "sense of relief."

"I thought the NCAA would see this how I saw it, how my teammates saw it, how my coaches saw it, how my family saw it, how anyone with any amount of brain activity would probably comprehend this," Gaines told Joe Rogan on his podcast. Nothing hateful about it, nothing even opinionated about it."

However, the NCAA said Thomas' participation in women's events was "non-negotiable," Gaines said.

"There was no questions that we could ask or concerns that we could raise. We were told we had to accept this with a smile on our face, . . ." she said. "We were told we fully had to treat this person as a woman."

Gaines remained silent, though, until she felt she no longer could.

Gaines and Thomas actually tied for fifth place in the 200-yard freestyle championship. "Incredibly embarrassing for a 6'4" man to not even be able to beat a 5'5" female," Gaines quipped. However, when it came time to receive trophies and go to the podium, the NCAA said they only had one trophy for the two swimmers, and gave it to Thomas.

Shortly afterwards, Gaines said the NCAA told her it was "crucial" that the trophy was in Thomas' hands during photos.

That's when Gaines, she says, "felt guilty for participating in the farce." When others in the crowd were celebrating Thomas, Gaines had an epiphany: "What in the world are we clapping for?"

So, Gaines was done being silent.

"How in the world as female athletes can we, as women, expect someone to stand up for us if we aren’t willing to stand up for us?" she said.

"I knew all season the unfair competition was wrong. I knew all season that the locker room aspect was wrong. I knew that the silencing that we were facing from our universities, I knew all of that was wrong. We all did. But it wasn’t until this official reduced everything that we had worked our entire lives for down to a photo-op to validate the feelings and the identity of a man, at the expense of our own. That’s really when I decided I couldn’t continue being silent."

Gaines has since founded the Riley Gaines Center at the Leadership Institute and hosts "Gaines for Girls" on OutKick.

A Honduran man at the U.S.-Mexico border in Eagle Pass, Texas, had a noticeable choice of attire during his journey into the United States: a t-shirt from President Biden's 2020 campaign.

In a conversation with Fox News, the man did not appear to know what "Biden Harris 2020" meant, asking who those people were, when questioned about where he had gotten the garment.

When the man, who was among a group who appeared to include women and children, was informed that they are the president and vice president, he came up with an explanation.

"Ahhhh. Then I have it on so they can let me in," the man said in response, before laughing. Others around him joined in on the laughter. The two groups were separated by barbed wire, with what appeared to be the Rio Grande behind the migrants. 

STATE OF THE UNION: BILL CLINTON WARNED ABOUT IMMIGRATION OVERWHELMING 'EVERY PLACE' IN AMERICA BACK IN 1995

The U.S. may be on the brink of a potential spring surge of illegal crossings at the southern border after U.S. Customs and Border Protection (CBP) sources told Fox News early Monday that migrant encounters had surpassed 21,000 over the course of three days.

The 7,000-plus migrant encounters on Sunday followed similar numbers on Friday and Saturday, the sources said.

Leading the encounters from Friday to Sunday was the Tucson sector in Arizona with more than 5,400, while the San Diego sector in California was the second busiest with more than 3,600, per the sources.

The increased numbers in Arizona and California appear to show that illegal crossing traffic is shifting away from Texas, where the Rio Grande Valley sector near Brownsville and the Del Rio sector near Eagle Pass saw among the fewest encounters, averaging 300 to 350 per day since Friday.

Last month, the Texas National Guard seized control of Shelby Park in the city of Eagle Pass and blocked Border Patrol from entering the area – part of Gov. Greg Abbott's effort to stop the surge of illegal immigration into Texas.
