A new television advertisement has sparked controversy in the debate over South Dakota's proposed abortion ban.

The first ad from The South Dakota Campaign for Healthy families, which opposes the abortion ban, features the story of Tiffany Campbell.

In 2006, Tiffany Campbell discovered that she was pregnant with twins who were suffering from Twin to Twin Transfusion Syndrome. She says it resulted in her having to abort one twin to save the other. Those who support the abortion ban say her message is misleading and partially false.

Tiffany Campbell says she's speaking out against South Dakota's abortion ban for other families faced with Twin to Twin Transfusion Syndrome.

"If this (ban) passes then they won't have the same option that we did to save a life," Tiffany Campbell said. "They will not be able to intervene and save one of their babies."

Dr. Glenn Ridder is the medical director for the Alpha Center, a pro life group. He supports the ban and contests the facts of the Campbell's story beginning with the premise that they needed to abort one of their twins.

"I don't know what procedure was done for this young lady who had the Twin to Twin Transfusion," Dr. Ridder said. "But the procedure that's nationally accepted now would not be declared an abortion."

Dr. Ridder is referring to a laser procedure designed to separate the blood vessels between connected twins. It's intended to save the life of both twins, meaning it would not violate the proposed ban. But the Campbell's say the laser procedure was not what their doctors recommended.

"We went through the testing to qualify for this laser procedure," Tiffany Campbell's husband Chris Campbell said. "We found out we really weren't good candidates for the procedure."

Instead, the Campbell's say their doctor's gave them a different option with better odds for saving one of their sons. The procedure is called Selective Cord Coagulation and involves stopping blood flow to the smaller twin through the umbilical cord. It led to the decision Tiffany addresses in her commercial.

"We had 24 hours to decide if we'd end one boy's life to save the other," Tiffany Campbell said in the advertisement.

"If it's someones advice to kill your offspring, that doesn't make a whole lot of sense," Ridder said. "And the studies prove out that it is not the healthiest choice."

Tiffany says, in her case, it was the healthiest choice, and if there was a better option, she says she would have taken it in a heartbeat.

"Brady was pumping blood for both of them, so his heart was failing at the strain," she said. "So every passing day that they were connected, Brady's heart was becoming weaker and weaker. So we didn't have time to say, 'Well we're going to give it five more days,' because he would have died, and then he would have taken Brady with him. That's how we made the decision to step in and end Brendan's life. I know I played a role in my son's death. I live with that every single day. But then I also look at Brady and I see why I had to do it."

Dr. Glenn Ridder has one other big problem with Tiffany's story. He says it doesn't apply to South Dakota's ban because doctors in this state do not perform the procedure she had done. That is true. The Campbell's actually flew to a fetal care center in Cincinnati, Ohio after finding out about their situation.

The South Dakota Campaign for Healthy Families has two responses to the argument. The group says the ban would take away the possibility of a doctor flying to South Dakota to perform the procedure if a mother is unable to travel. They also say that supporters of this ban intend to make it a national issue.
