Liberal group presses NBC to run anti-Keystone pipeline ad

The liberal group Credo Action has launched an online petition urging a Washington, D.C., NBC station and its corporate parent to “stop censoring” billionaire climate activist Tom Steyer’s anti-Keystone XL pipeline ad.

The petition, available here, follows NBC-owned WRC-TV’s rejection of an ad Steyer tried to have air during Tuesday’s "Tonight Show" episode that featured President Obama as a guest.
