“Now more than ever, we must unite to uphold the truth and biological reality established by God that there are only two sexes,” said Miller. “I am proud to stand alongside Senator Marshall in introducing the House companion to the Defining Male and Female Act to ensure our nation upholds common sense and puts an end to the Left’s dangerous and extreme sexual fantasies.”

“The Democrats’ radical transgender agenda is dangerous and wrong. We shouldn’t need legislation to tell us the basic reality that there are only two sexes, but here we are,” Marshall said. “I’m thankful President Trump has made this a top priority and signed an Executive Order on his first day in office recognizing that there are only two sexes. Congress must ensure this historic action is written into law by passing the Defining Male and Female Act.”

Trump’s directive was issued on his first day in office on Jan. 20, with the intention to protect female sports from those who were born male but claimed to be female. The executive order stressed the importance of protecting women’s athletics while also stressing the importance of maintaining the “biological reality of sex.”

“Across the country, ideologues who deny the biological reality of sex have increasingly used legal and other socially coercive means to permit men to self-identify as women and gain access to intimate single-sex spaces and activities designed for women, from women’s domestic abuse shelters to women’s workplace showers,” read the president’s executive order. “This is wrong. Efforts to eradicate the biological reality of sex fundamentally attack women by depriving them of their dignity, safety, and well-being.” 

“The erasure of sex in language and policy has a corrosive impact not just on women but on the validity of the entire American system,” the order noted. “Basing Federal policy on truth is critical to scientific inquiry, public safety, morale, and trust in government itself.”

The legislation proposed by Miller and Marshall expands on the previous executive order and reinforces its values. According to a joint release issued by the two Republicans, the decision to do so is rooted in “science and common sense.”

“This bill establishes clear, consistent definitions of male and female, reinforcing that federal law must uphold and reflect science and common sense,” read the release. “It aligns with President Trump’s day-one executive order, which made it official government policy to recognize that there are only two sexes, based on biological reality established by God.”
