The latest smattering of fast falling flakes to blanket the area could not keep advocacy-minded entertainers away from the Capitol on Tuesday. And there’s still more help from Hollywood already on the way.  

Actress-turned-animal-rights-activist and former Elvis spouse Priscilla Presley made the rounds on behalf of the Humane Society, stumping for equine rights and relief from soring.  

A tipster placed Presley at neighboring 701 Restaurant the night before, sharing that the world famous “Naked Gun” co-star broke bread for several hours with friends at the pol-pleasing establishment .  

Paul Williams, ’70s-songwriter-turned-president and chairman of the American Society of Composers, Authors and Publishers, proved that he’s still a big man on this campus by tag-teaming pressers across Capitol Hill.  

Williams helped usher in the new Library of Congress exhibit, “ASCAP: One Hundred Years and Beyond” and shared his thoughts with lawmakers about music royalties.  

Bono, meanwhile, didn’t make it all the way to the halls of Congress — sending, instead, 250-odd friends to share his concerns with lawmakers.  

A tipster said the U2 frontman surprised members of his ONE Campaign by popping into town Feb. 22 for a brief visit during which he “thanked the volunteers for their time and dedication to the fight against extreme global poverty.” The pep talk must have worked: ONE aides from more than 44 states were expected to take 222 meetings with House and Senate staffers Tuesday.  

And the celeb worship is far from over.  

Come Wednesday, the Dirksen Senate Office Building will be the place to be, thanks to dueling hearings featuring a pair of Tinsel Town heavies.  

Actor/screenwriter Seth Rogen kicks things of at 2 p.m. by joining ex-Rep. Dennis Moore, D-Kan., for the second round of questioning during a Senate Appropriations Subcommittee on Labor, Health and Human Services, and Education hearing about Alzheimer’s. Rogen, whose mother-in-law has the debilitating disease, serves as a “celebrity champion” for the National Alzheimer’s Association.  

Not to be outdone, the Senate Foreign Relations Committee has snagged Academy Award-winning director — and the next in line to don Batman’s iconic cowl — Ben Affleck for a discussion poised to begin at 2:15 regarding peace prospects in the Republic of Congo. Affleck co-founded the philanthropic Eastern Congo Initiative in 2010.
