Guest mixologist Rachel Maddow serves David and Susan Axelrod

WHCInsider has the exclusive news: Party powerhouse MSNBC, coming off an already legendary 2009 Radio and TV Dinner after party, is taking on the Bloomberg | Vanity Fair juggernaut in 2010 for the White House Correspondents Dinner on Saturday, May 1.

The White House Correspondents weekend is a time for the networks and their print counterparts to entertain their clients, show celebrity muscle, and bring Washington elites together. There is no more competitive time slot that weekend than the Saturday after party sweepstakes, dominated for years by Bloomberg.

Jason Binn’s Capitol File magazine began their own after party in 2008 to much success. With a breathtaking cover featuring new D.C. residents—Obama’s Valerie Jarrett and Desiree Rogers—Binn gathered top politicos in 2009, after hitting the dance floor in 2008.

MSNBC, which has enjoyed much ratings success and made itself a primary player in the Washington political media culture, will give everyone a run for their money this year.

MSNBC’s party will be created by top event producer, Philip Dufour, mastermind of the Radio and Television after party. If you are one of the lucky few to receive an invitation, we’ll see you at the Mellon auditorium.

Capricia Marshall and family with Sec. Hillary Clinton

The Ben Franklin Room of the State Department was filled with stars and stargazers, as well as family and friends, as Secretary Hillary Clinton presided over the swearing-in ceremony for her longest-serving aide, Capricia Penivac Marshall, as chief of protocol.

Marshall, the former Clinton White House social secretary and campaign veteran, came to Washington with the Clintons in 1992. Secretary Clinton shared a hilarious Inauguration story about Marshall being stuck outside the White House gate.

It wasn’t just Clinton friends. Top Obama pals Valerie Jarrett, Desiree Rogers, and First Lady Michelle Obama’s Chief of Staff Susan Sher, were there to pay tribute to the newest executive in charge of diplomatic activities for President Obama. Roger’s deputies Ebs Burnough and Joe Reinstein had a crowd of admirers lined up to say hello.

CLICK here to see Marshall’s official list of duties.

Marshall’s protocol team includes some Washington’s savviest veterans, including deputies Lee Satterfield and Dennis Cheng. Her team debuts on the world stage this month with one of the biggest diplomatic gatherings of the year: the G-20 meeting in Pittsburgh.

Obama State Department Ambassadors Elizabeth Bagley (Global Partnerships) and Melanne Verveer (Global Women’s Issues) added their shine to the large crowd. Clinton family members, from mom Dorothy to daughter Chelsea, cheered for their close friend. Marshall’s 9-year old son Cole mugged and husband Rob Marshall looked shocked by Clinton’s shout out to him as “the best cardiologist in the world.”

Parents Frank and Mary Penavic beamed and assorted cousins from her hometown of Cleveland, Ohio, watched the ceremony.

Former protocol ambassadors Lucky Roosevelt, Lloyd Hand, Lea Berman, Evan and Kit Dobelle joined former White House Social Secretary Ann Stock and veterans of other administrations in their own mini-reunion

Celebrity guests included: Greta Van Susteren and her husband John Coale, Mandy Grunwald, Janet Howard, Ann Orr, Claire Shipman, Michael Feldman, Melissa Moss and her husband Jonathan Silver.

Pam Stevens, once Condoleezza Rice’s press secretary and now press adviser to Ambassador Nancy Brinker and Race for the Cure, caught up with old friends as Betsy Fischer and other media types worked the room. New York’s fabulous event planner, and Marshall pal, Bronson Van Wyck drew his own crowd.

Terry McAuliffe had a double-barreled receiving line around him; no surprise there. He also hosted a Friday night gathering at his McLean home.

Sally Quinn told me that she remembers reading the original newspaper stories about Big Edie, Jackie Kennedy’s aunt, and Little Edie, Jackie Kennedy’s first cousin, living in the dilapidated estate, Grey Gardens, the home Sally now owns in East Hampton. Here is Sally’s story from today’s Washington Post.

When Washington favorite, HBO Co-President Richard Plepler (who began his career as an aide to Senator Chris Dodd) comes to town, the stars some out … and the dinner and screening at The Motion Picture Association Wednesday night was no exception. George and Elizabeth Stevens, Al Hunt and Judy Woodruff, Elsa Walsh, Margaret Carlson, and the Washington Post dream team Marcus Brauchli with his wife Maggie Farley, and  Raju Narisetti were all on hand.

And Obama friend and White House Social Secretary Desiree Rogers joined the party, which included of course, Ben Bradlee, Sally Quinn, and their first-time author son, Quinn Bradlee … who didn’t seem to suffer any wear-and-tear from his grueling book tour schedule.
