A Hill source tells us Sen. Cory Booker (D-N.J.), a celebrity fave, was spotted Wednesday afternoon lunching in the Senate Members Dining Room with weatherman Al Roker. We’ve reached out to Booker’s office to see what the two were talking about, other than, of course, the weather.

We did receive this confirmation through Roker’s Twitter feed that he is in fact on Capitol Hill (and so is Barbra Streisand, by the way). Like most Hill tourists, Roker seemed most taken by the Senate underground monorail. Roker captured this video of what appears to be Sen. Tom Harkin (D-Iowa) riding the train.

We don’t know much about Roker’s politics — a quick FEC search didn’t show him contributing to any campaigns — but when we think of Roker and Washington, we can’t help but recall this stomach-turning story of the TV personality’s visit to the White House.

Let’s just say we hope he was “very vigilant with what he” ate over lunch.
