WASHINGTON — Donald Trump Jr. on Monday derided a transgender cyclist who won a women’s championship.

The president’s eldest son tweeted an article about the cyclist, who set a women’s world record but wouldn’t have qualified for the men’s competition.

“You can never be woke enough!” Trump Jr. tweeted. “Sorry to all female athletes who spent their lives mastering their games.”

Rachel McKinnon, who was born a biological male, defended her title in the 2019 Masters Worlds in Manchester and set a new world best time. Her win has set off debate on the fairness of trans athletes competing in women’s sports.

McKinnon defended her right to compete to Sky News.

“By preventing trans women from competing or requiring them to take medication, you’re denying their human rights,” the Canadian athlete said.

Trump Jr. retweeted another comment from a self-described Christian conservative mom, @therightmelissa, that said: “The ultimate male privilege is men being able to dominate women’s sports. All the gains women have made toward equality flushed.”

“It’s funny because it’s true,” Trump Jr. added. “Sad.”
