A bill in front of Pennsylvania's House would require women to undergo an ultrasound before undergoing an abortion.
Unlike similar bills in other states, the Pennsylvania bill would not require an internal probe.
Republican Governor Tom Corbett said he would oppose requiring such invasive procedures, but said he sees no problem with a mandatory ultrasound.
"I don't know how you can make anybody watch, because you just have to close your eyes," said Corbett. "But as long as it's on the exterior, not interior."
A committee approved the bill last fall, but a top House Republican said concerns raised by the medical community will need to be addressed before it's brought up for a floor vote.
The legislation would require the ultrasound screen to be within the woman's eyeshot. Abortion providers would have to note whether or not women look at the screen.
