In a statement Oregon Right to Life sent LifeNews.com on Thursday the group said Erickson has "betrayed the trust of his former girlfriend, prominent political organizations and every Republican voter in the 5th Congressional District."

Gayle Atteberry told LifeNews.com that she was aware of the allegations two years ago when Erickson approached her group seeking an endorsement in a previous election.

"However, as the Election Day drew near, we heard from Tawnya, a young woman who claimed to be the mother of Mike's child, one she ultimately aborted with Mike's aid and money. We talked personally with Tawnya. She is very credible and remains, to this day, devastated over the events," Atteberry said.

"When we approached Mike about these allegations, he admitted giving her money and dropping her at a 'doctor's office'", Atteberry added. "He said he did not know she was getting an abortion."

"Now, less than two years later, Mike Erickson issues a flat denial about everything, even the parts he openly admitted in our presence," the pro-life advocate said.
