Only a day after reports that Gingrich would put up a Web site seeking pledge money for a presidential campaign, an aide now says that he is backing off and will not run, after all.

"He will continue to bring the American people solutions to the challenges America faces through American Solutions, not as a candidate for president," said Gingrich spokesman Rick Tyler, in a phone interview with CNN.

Tyler said that Gingrich realized he could not run his American Solutions political action committee and form a presidential exploratory campaign at the same time.
