Reliable Sources brings word that Fox News’ spot in the White House press room is being challenged once again–this time by Bloomberg News’ Managing Editor, Al Hunt.

Bloomberg (via Hunt) claims–in shades of CNN’s previous reasoning–they’ve been around longer, are more established and “[w]e write about matters financial and non-financial.” Fox News’ Vice President of News and Washington Managing Editor Bill Sammon’s plan relies on a 2007 I.O.U. from the last press room restructuring and the assumption that Bloomberg still covers just finances. The Huffington Post has the full letters here.

There’s no buzz on whether this late Bloomberg bid will work, but at least we have a Fishbowl DC poll. And in case you forget the prime real estate in question, check out WHC Insider’s press room seating chart.

Alan Krueger and Billie Jean King

The Washington Kastles held their first annual celebrity tennis match to benefit the American Red Cross on the final night of the Washington Kastles season … and crowned Obama’s Assistant Treasury Secretary MVP. Alan Krueger joined media and political celebrities — Sen. Evan Bayh, Fox’s Bret Baier, CNN’s Ed Henry and ABC’s Jonathan Karl — coaching on the sidelines: Billie Jean King and the GEICO Caveman.

Bloomberg’s Al Hunt and Margaret Carlson called the game in a Washington version of the Wimbledon voice over. Celebrity ball kids included Patrick Henry (8), David (8) and Rachel (10) Greenberg, Betsy Fischer’s daughter Ella (8), and Jonathan Karl’s girls Anna (9) and Emily (12).

Alan Krueger

With Redskins superstar Darrell Green and tennis great Ilana Kloss, it was hard to imagine that a former Princeton economics professor would be the breakout star of the first annual celebrity tennis match to benefit the American Red Cross on the final night of the Washington Kastles season.

Alan Krueger, Assistant Treasury Secretary for Economic Policy, impressed his team and his media/political opponents — including Senator Evan Bayh, Fox’s Brett Baier, CNN’s Ed Henry and ABC’s Jonathan Karl. Coaching on the sidelines: Billie Jean King and the GEICO Caveman.

Insiders were disappointed that Washington fav Gene Sperling had to cancel his appearance due to meetings, but Kreuger was the tournament’s MVP. Kastles owner Mark Ein has expanded the reach of the franchise, only in their second year, and with this first-ever charity celeb match has created a new Washington tradition.

She wowed the crowed, which included: NBC’s Betsy Fischer and Luke Russert, Bloomberg’s Al Hunt and Margaret Carlson, Newshour’s Judy Woodruff, Larry Summers from the White House NEC, and venture capitalist and Kastles’ co-founder Mark Ein (those are the Fenty boys next to Mark).

And Serena showed everyone what they came to see — some great tennis. Serena won her Singles match 5-2 (against Marie Eve-Pelletier), she and Rennae Stubbs won their Doubles match 5-1, and Serena and Leander Paes ran away with the Mixed Doubles match 5-0.

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.
