From the AP via Yahoo:
The Republican National Committee approved a resolution Friday to block two television networks from hosting GOP presidential primary debates.
Friday’s vote affirms RNC chairman Reince Priebus’s threat against CNN and NBC unless the networks dropped plans to air programs about possible Democratic presidential contender Hillary Rodham Clinton. The vote was unanimous.
