There were repugican members of Congress involved in O’Keefe NPR sting

In Howie Kurtz's new piece on the Daily Beast, one of James O'Keefe's former colleagues in deception suggests that O'Keefe was coordinating his NPR undercover sting with members of Congress, as it was intended to influence NPR's budget battle on the Hill:

But Templar says O’Keefe told him the video had to be released within three days because he was in touch with sources in Congress and a vote was about to be taken on a budget resolution that could eliminate federal funding of NPR. O’Keefe said he had been assured that "this story would push it over the edge,” according to Templar.
