McCain, the Republican party's 2008 presidential nominee, will travel to New Hampshire to endorse Romney who is coming off a victory in Iowa’s caucus on Tuesday night.
McCain and Romney had a heated contest for the state in 2008 where Romney criticized the senator for voting against the 2001 Bush tax cuts while McCain hammered Romney as the "candidate of change," highlighting shifts on policy. But the relationship healed after Romney aided McCain's campaign against Obama and in his 2010 Arizona senate race where he faced a primary challenge from former Rep. J.D. Hayworth.
The Hill reported in early December that McCain was moving towards endorsing Romney but the account was disputed by the senator's office.
Polls show Romney who owns a vacation home in New Hampshire and was governor of neighboring Massachusetts well ahead in the state. On Tuesday, the daily Suffolk University/7News tracking polling found him holding steady with 43 percent support from likely GOP primary voters.
Romney was followed by Ron Paul at 16 percent, Jon Huntsman holding steady in third place at 10 percent and Newt Gingrich with 9 percent.
Rick Santorum who lost Iowa to Romney by only 8 votes, the closest caucus margin in modern American history is at 5 percent in the state.
McCain’s backing also adds to Romney’s edge in lawmaker endorsements giving him 62. Romney has also secured the support of New Hampshire Sen.
