The panel that was set up to investigate the terror attacks in libya that killed four americans, including ambassador christopher stevens. Committee investigator Bradley Podliska was fired, but he and the Committee Chairman disagree heres nancy cordes. Reporter podliskas claims are another blow to the house benghazi investigation, but republicans say hes lying. The air force reservist says he was fired as an investigator for the committee because he refused to focus solely on former secretary of state Hillary Clinton and her emails. Investigation. I honestly do not believe this investigation was set up to go after hillary. I believe it shifted that way. Reporter but republican trey gowdy who chairs the Committee Said podliska was terminated in part because he himself manifested improper partiality against clinton. He says podliskas accusations came only after he demanded money from the committee in mediation, and the committee refused to pay. Democrats say it is more proof that the committees chief goal is to destroy the likely democratic nominee. They say the House Majority leader all but confirmed it when he said this everybody thought hillary but we put together a benghazi committee. What are her numbers today . Reporter internal documents obtained by cbs news show that the committee originally planned to hold nine hearings this year to hear from eyewitnesses, intelligence defense. But none of those hearings has taken place, and only one is scheduled with clinton as the lone witness later this month. On 60 minutes last night, president obama argued the scrutiny of clintons private server has been overblown. She made a mistake. Shes acknowledged it. I do think that the way its been ginned up is in part because of politics, and i think shed be first to acknowledge that maybe she could have handled the original decision better and the disclosures more quickly. Reporter republicans say theyve had to scrap some of the hearings theyve had planned because they have had difficulty procuring some of the relevant documents from the obama administration. Scott, they say they always intended to do most of their work behind closed doors. Committee has been going on for nearly 18 months. Now nancy cordes in our washington newsroom. Nancy, thank you.
