Louisiana Gov. Bobby Jindal (R), in a speech Saturday at Liberty University, will attack HGTV for cancelling a show hosted by a pair of brothers who have spoken out against homosexuality.

The Benham brothers -- twins David and Jason -- told CNN on Thursday that they lost the show after a liberal Web site posted audio of David Benham talking about how "homosexuality and its agenda that is attacking the nation." The site also noted David Benham led a prayer outside the Democratic National Convention in protest.

According to advance excerpts, Jindal will say in his commencement address Saturday that the decision to cancel the show is the latest example of liberals trying to silence conservatives for their religious beliefs.

"Think about that for a minute," Jindal will say. "If these guys had protested at the Republican Party convention, instead of cancelling their show, HGTV would probably have given them a raise."

The brothers are graduates of Liberty University, the same evangelical Christian college where Jindal is set to speak. They will be present at the address, as guests of university president Jerry Falwell Jr.

Jindal previously defended another conservative on TV, "Duck Dynasty's" Phil Robertson, after Robertson labeled homosexuality as sinful and suggested Jim Crow laws weren't that bad. The show's network, A&E, first suspended and later reinstated Robertson.

Here's the Benham brothers' interview on CNN:
