Wendy Davis, the Democratic Texas state senator running for governor, reveals in her upcoming memoir the heartbreaking decision she made to terminate a pregnancy due to a fetal brain abnormality, according to the San Antonio Express-News.

Davis wrote that in 1997, she and her then-husband, Jeff Davis, both wanted the baby girl, which they had already named Tate Elise. But after doctors found Tate had an acute brain disorder that would likely cause her to suffer, the Davises decided to terminate the pregnancy.
