From ABC News:

Mitt Romney to Endorse John McCain

February 14, 2008 1:32 PM

ABC News' George Stephanopoulos and John Berman Report: Former Gov. Mitt Romney, R-Mass., is planning on endorsing his former Republican rival Sen. John McCain, R-Ariz.

A source familiar with the decision said the endorsement will take place this afternoon at Romney for President headquarters in Boston at 3:30pmET.

Romney will ask his delegates to support McCain, the presumptive Republican presidential nominee.

The former governor made his decision to endorse today in the interest of helping McCain gain the 1,191 delegates he needs to secure the party nomination and unite the party for the general election against the Democrats in November.

Romney campaign manager Beth Myers notified McCain campaign manager Rick Davis in a telephone call today of Romney's decision, and they immediately made arrangements for an announcement in Boston this afternoon since McCain was campaigning in Rhode Island today.

After McCain's townhall meeting near Providence this afternoon, the campaign is flying to Boston for the endorsement.

Romney and McCain will meet today before they both announce the formal endorsement at a press conference.
