◼ USA TODAY interview: Gingrich ready to support Romney - Susan Page/USA TODAY
Former House speaker Newt Gingrich, on the eve of suspending his roller coaster presidential bid, said in an interview with USA TODAY that he will embrace Mitt Romney's candidacy Wednesday and is ready to campaign for his former rival.
The two men will make a joint appearance in a few weeks, when Gingrich will make an official endorsement. The Romney campaign and the Republican National Committee have offered to be helpful as Gingrich works to retire his campaign debt.
In a phone interview Tuesday, Gingrich said he had no regrets about his decision to run for president, but "I have regrets about not being smarter about how to run."
