CNN reports:

Former New Jersey committeman David Norcross, something of a ringleader within the RNC’s anti-Steele crowd, co-authored a message Tuesday to the committee’s 168 members endorsing Wisconsin GOP Chairman Reince Priebus. The message was co-signed by former Wisconsin committeeman Michael Grebe.
Norcross and Grebe heaped praise on Priebus for his work electing Republicans in Wisconsin and said he proved his mettle nationally while serving as RNC General Counsel under Steele. . . .
Another committee veteran and Steele critic, Iowa committeeman Steve Scheffler, told CNN Tuesday he is also backing Priebus.
