Red, White and Blue, a Houston political pubTV show, is back on the air at KUHT after a months-long controversy. The show, one of the few on local politics, featured one Republican and one Democratic host. It had been suspended after last year’s election. Politicians got involved, asking for the show to be reinstated. And now it has been. The first of the new weekly episodes runs at 8 p.m. tonight, and again at 5 p.m. Sunday.
