The House Ethics Committee said Monday it will not appoint a special panel to investigate allegations that Rep. Cathy McMorris Rodgers, the fourth-highest ranking House Republican, improperly combined campaign and official funds in a GOP leadership race and her re-election campaign.

The committee’s top two leaders, Reps. Michael Conaway, R-Texas, and Linda Sanchez, D-Calif., said they will not formally drop the case against McMorris Rodgers, but will continue to review the matter under their own authority. In practical terms, the decision means it is unlikely that McMorris Rodgers will face charges or sanctions.
