Possible VP Pick Rob Portman Visits Mitt Romney Turf

Sen. Rob Portman, R-Ohio, is on a fundraising, Mitt Romney-advocating roll with events taking the rumored vice presidential contender suspiciously close to the presumptive Republican nominee and his team over the weekend and into next week.

Portman has not appeared with Romney since his swing-state bus tour last month. However, Portman's two events Saturday in Concord, N.H., on behalf of Romney, put him just a 45-minute drive from Wolfesboro, where Romney and his family have been vacationing all week at their lakeside compound.

ABC News has also learned that Portman will host a $1,000-a-head fundraiser for Romney Monday night in Boston, not far from Romney for President headquarters.

Could an in-person meeting between Portman and Romney or Romney's vetting team be in the cards? Portman told reporters Saturday he had not met with Romney in Wolfesboro and had "no plans" for a face-to-face meeting before Romney's vacation is over.

Coincidentally, Romney's vacation is technically over Sunday when he jets to the Hamptons for a full day of fundraising and then back again to New Hampshire where he will overnight. With Portman still in the area for a fundraiser, could a meeting happen then?

Portman emphasized the main purpose of his trip was a college tour with his daughter.

And while the Ohio Senator would not speak to whether he was even being vetted, one thing is for sure: Until the VP is announced, they'll be a lot more tea leaf reading to come.
