A group allegedly based in Tennessee, Restore America, helped with an unsuccessful challenge to Oregon's domestic partnership law. Opponents of the law passed by the Legislature attempted to get enough signatures to bring the issue to the ballot. The Oregon Secretary of State ruled that they failed in their effort, a decision upheld by a federal appeals court.
"This was a backdoor attempt by out-of-state interests to overturn a law passed fair and square," said state Rep. Tina Kotek, D-Portland, who supported the domestic-partnership law.
Restore America's website shows an Oregon address as does their 2006 990.
Update: Apparently the executive director lives in Tennessee.
