It was shrouded in secrecy, but some immediate details are coming out from the meeting held this morning between presumptive GOP nominee, Mitt Romney and his former rival Rick Santorum.

The met alone, face to face and without staffers during the 90 minute meeting at an office overlooking the city of Pittsburgh and belonging to one of Santorum's oldest advisers, John Brabender.

"I know there wasn't a list or talking points," Brabender said, referring to the agenda of the private meeting. "It was meant to be a casual conversation. It seemed friendly."

Brabender joked there was "was no screaming, kicking or fighting," and more seriously noted an endorsement was never expected out of the meeting.

"There was always an expectation it was would take a little bit of time," Brabender said, referring to the tete a tete. "It was shorter than any of the debates. There was a lot they both wanted to talk about and they both value each other's opinion. It was a reasonable amount of time."

The meeting ended just before noon, allowing Romney to make his 12:15 event in O'Hara, a suburb right outside of Pittsburgh.

Romney said Friday morning that he "expect(s) you're going to us all come together," when asked on Fox News about the meeting with Santorum.

But the two did not appear together in O'Hara and Santorum has not endorsed Romney.

Romney said on Fox that he didn't expect an endorsement today, but again stressed that "all Republicans will come together in the final analysis and support my candidacy."

"You see in our party a great deal of enthusiasm about making sure we get America back on track and we start creating the jobs that the American people are looking for," Romney said.

"We said so on the stage when we were running in debates against one another," Romney said. "I think the key thing is we're going to come together and get this economy going."

On MSNBC, earlier Friday former Santorum press secretary  Alice Stewart was asked about the two uniting in a more formal way. She said the informal meeting "is a great start."

The two have a great respect for each other," Stewart said.
