Republican state Sen. Richard Briggs co-sponsored a Tennessee bill that would codify some of the country's most austere abortion restrictions. He says he never thought it would actually become law.

Five years ago, when state Sen. Richard Briggs co-sponsored legislation that would codify some of the country’s most austere abortion restrictions in Tennessee – it seemed to him like little more than political theater.

“The truth was I thought it would never come to be,” he says.

But three years later it did come to be. The Tennessee state law was triggered after the Supreme Court overturned Roe v. Wade and ended the federal right to abortion. The state law established strict abortion bans and potential criminal penalties for doctors who violate them.

Now Briggs is fighting an uphill battle to undo some of the legislation he helped to put into place. It’s a battle that some experts say could be instructive for the rest of the country.
