Public broadcasting's top GOP backer switches sides

The top Republican supporter of federal funding for public broadcasting not longer appears to support this outlay.

Rep. Mike McCaul (R-Texas) had previously served as the co-chair of the bipartisan public broadcasting caucus. 

"As a father of five children, I have been supportive of PBS children's programming in the past," he said. "However, the recent events involving NPR undermine their claims of objectivity in their reporting. Because NPR has crossed the line to political bias, I will no longer serve on the caucus."

McCaul voted in favor of defunding the Corporation for Public Broadcasting by supporting the Republican Continuing Resolution that passed the House last month.

Public broadcasting dollars have come under fire as Congress works to rein in spending. The Obama administration and many congressional Democrats support the funding, while Republicans want it ended.

The funding has received additional scrutiny this week after an NPR executive expressed highly partisan remarks in a secretly recorded video, leading NPR chief executive Vivian Schiller to resign.
