Rep. Michele Bachmann of Minnesota said Tuesday that she has recently spoken with likely Republican nominee Mitt Romney, though she did not offer an endorsement of her one-time rival.

In the appearance on CNN's "John King, USA," Bachmann said she sees the GOP coming together, and wants to be "a voice of uniting our party."

"I'm very excited with what I'm seeing, not a lot of bumps in the road, but I'm very excited about bringing factions together," she said. "This doesn't happen overnight. We're in the process of coalescing and uniting and it's all in due time."

In mid-March, she told CNN's Wolf Blitzer that the party needed to "unify and unify quickly." She said she would "back whoever the people choose."

On Tuesday, Bachmann said she recently spoke with Rick Santorum, who ended his GOP presidential run earlier this month, and Romney, though she did not divulge the nature of the conversations.

She told CNN Chief National Correspondent John King that Romney's vice presidential pick should have pro-life positions, and asked if she should be on the list, she deferred to Romney.

"Well, he'll make his decision, that's up to the governor," she said. "We trust him to make the wisest decision for our team and for our party. And we know that he'll do that."
