At the Texas statehouse Monday afternoon, pro-life counter-protesters challenged pro-choice activists rallying to defeat a state ban on abortions after 20 weeks.

A live streaming video of the scene at the state capitol showed pro-life activists singing the hymn “Amazing Grace” to drown out pro-choice chants opposing the bill.

Texas Gov. Rick Perry, R-Texas, called a second special session of the Texas legislature to pass the late-term abortion ban bill after Texas state Sen. Wendy Davis, a Democrat, successfully filibustered the bill last week.
