A Utah senator is working on legislation that would require doctors to administer anesthesia to a fetus before an abortion based on the premise that the fetus can feel pain.

Sen. Curt Bramble, R-Provo, requested that legislative staff begin drafting the bill Tuesday. He says he's still determining at what point in the gestational process the rule would apply.

Montana lawmakers passed a similar law in 2015 requiring fetal anesthesia before surgeries, including abortion, after 20 or more gestational weeks.

Montana's Democratic governor later vetoed the measure.

Karrie Galloway, CEO of Planned Parenthood Association of Utah, says Bramble's proposal would insert a political opinion into a woman's private medical decision.
