WASHINGTON (AP) - Mitt Romney is working to win over his former rivals.

Romney is scheduled to meet with former foe Rick Santorum on Friday and is ready to pick up Newt Gingrich's endorsement this week. The one-time rivals are expected to eventually fall in line behind the expected Republican presidential nominee.

But both Santorum and Gingrich are looking for assurances first.

Santorum wants to make sure conservatives' priorities are reflected in Romney's campaign. He is looking for assurances from Romney during a private meeting but isn't expected to offer an immediate endorsement.

And Gingrich wants to repair his reputation within the party, as well as pay down at least $4.5 million in campaign debt.
