Texas Attorney General Ken Paxton is splitting with the state GOP over in vitro fertilization after it became a line of attack in his battleground Senate race.

Paxton stated a more centrist position on IVF as polls show a tight race ahead of the November general election, saying he supported the procedure. The development sets him at odds with the Texas Republican Party, but in line with President Donald Trump, the self-proclaimed “father of fertility” who endorsed his Senate campaign against Democratic rival James Talarico last month.
