He's had a while now to open an investigation.
He won't do it. Why? Because such an investigation (in part) would lead to the question...why didn't HE object to the counting of the E.C. votes when he (& the rest of the 111th Congress) knew darn well there were significant questions being raised across the country. Guaranteed he received calls, emails and letters from his constituents regarding Barry's eligibility.
He did nothing then, he'll continue to do nothing now because he's part of the problem when it comes to this issue. He, nor any other politician from the 111th Congress, will (essentially) investigate himself.
“He won't do it. Why?”
Opposition research cuts both ways! Issa has skeletons in his closet. Big ones, apparently. Democrat operatives launched a media campaign to open up Issa’s questionable business dealings back in January, but pulled back when Issa backed off of any discovery of Obama’s BC or anything too close to Obama.
