Former Massachusetts Gov. Mitt Romney (R) said Monday that he saw no controversy in a supporter's use of a shell company to donate $1 million to a super-PAC supporting Romney's presidential candidacy.

Romney wouldn't condemn Edward Conrad, a former executive at Bain Capital, the company Romney co-founded, for setting up a company to contribute the bulk sum to the Restore Our Future PAC.

Conrad revealed himself over the weekend as the individual who set up W Spann LLC, a corporation that was founded this year and dissolved shortly after contributing to Restore Our Future, a super-PAC that can receive and spend unlimited amounts of money that was founded by veterans of Romney's 2008 presidential campaign.

"I think he came out and discussed who he is," Romney said in New Hampshire, adding that he saw "no controversy" because Conrad had identified himself.

Conrad had been a previous contributor to Romney and other companies, but left-leaning watchdogs had asked the Federal Election Commission (FEC) to investigate the mysterious donation after NBC News brought the donation to light.
