Texas Attorney General Ken Paxton waded into a high-profile legal battle on Tuesday between a surrogate and a California couple over an unborn baby’s access to lifesaving healthcare, which has captivated anti-abortion activists.

Paxton, who is running for Senate, filed a petition to intervene in the Texas court case between surrogate McKenna West, an Alaska resident who traveled to Texas to get treatment for the unborn baby’s heart defect upon his birth, and a California couple, Nausheen Gilkar and Omar Ahmed, who are the intended parents of the unborn child and have filed a different lawsuit in California court seeking to have West deliver the baby in the Golden State.
