A mysterious corporate donor to an outside spending group supporting Mitt Romney's campaign for president isn't a corporation at all, but a former executive of Romney's old employer, Bain & Co., and his wife, according to records.

Super PAC "Restore Our Future" reported a $250,000 donation from a firm called Glenbrook LLC on its disclosure report released Jan. 31. On Tuesday, the group amended its filing, dropping Glenbrook and replacing it with the names Jesse and Melinda Rogers.

Both are listed as having made $125,000 contributions. Jesse Rogers works in "investment management" at Altamont Capital Management. Melinda Rogers' occupation is listed as "homemaker.".
