DENVER (AP) — Colorado Right to Life said it was kicked out of the National Right to Life coalition on Wednesday, in part for publicly criticizing Focus on the Family founder James Dobson.

The Colorado group and three others accused Dobson of misrepresenting a Supreme Court decision that upheld a ban on dilation-and-extraction procedures, called partial-birth abortion by opponents.

Dobson had praised the ruling as a victory for abortion foes, but the Colorado group believes it will only encourage doctors to find other, “less shocking” methods. It joined other organizations in running full-page ads in at least two newspapers criticizing Dobson.

Leslie Hanks, vice president of Colorado Right to Life, said the national coalition expelled the Colorado group because of those ads and because of what she called the Coloradans’ more “confrontational” approach.

“We’re in discussions with another organization we feel better aligns with our perspective, and we intend to carry on,” Hanks said. She would not identify the other group.

A spokeswoman for National Right to Life did not immediately return a call.

The ads ran in The Washington Times and in The Gazette of Colorado Springs, the city where Dobson’s conservative Christian ministry is based.
