Mark Hamill says the force is strong with this White House, appearing at a press briefing to cap off the week and sing the praises of President Biden, whom he’s already nicknamed.

The legendary actor surprised the press corp Friday — appearing alongside press secretary Karine Jean-Pierre and explaining how he got to meet the prez … highlighting some of his legislative accomplishments.

Hamill eventually opened up the floor to questions — with one reporter asking about MH’s meeting with POTUS. While he’s cagey on exactly what he and Biden talked about, he does admit he christened JB as “Joe-B-Wan Kenobi” — and it got a laugh out of the room.

Hamill admits this wasn’t his first trip to the W.H., saying he also stopped by the Carter and Obama White Houses … but, this meeting sounds more intimate — totally out of this world.

Like we said … the visit comes a day before May 4th — a holiday for Star Wars fans — so, looks like a smart PR move on the White House’s part to drum up some attention and support for the President as he heads into a tough election cycle.

Of course, it probably wasn’t a hard get. Hamill’s a lifelong Democrat supporter … and, he’s taken lots of big shots at Biden’s general election opponent, Donald Trump, in the past.
