Kathy Griffin? The kooky comic was spotted at L2 on Friday night. Griffin, who had just wrapped a performance at the Kennedy Center, made a surprise appearance at the Georgetown club to wish CNN’s Jessica Yellin a happy 40th birthday and hang with her pals and parents-to-be, CNN’s John King and Dana Bash. Other guests at Yellin’s birthday bash included NYT’s Jeff Zeleny, TIME’s Jay Newton-Small, Doug Heye, NRSC’s Brian Walsh, Jack and Susanna Quinn, Mark Cuban, Kimball Stroud, Treasury spokesman Mark Paustenbach, CNN’s Brianna Keilar, NYT’s Carl Hulse, HuffPo’s Peter Cherukuri and SKDK’s Emily Lenzner, NBC’s Savannah Guthrie and GPG’s Mike Feldman, NYT’s Mark Leibovich, NBC’s Betsy Fischer and Politico’s Jonathan Martin, W.H. Dep. Social Secretary Ebs Burnough and Wolf Blitzer who graciously posed for pictures with a posse of L2 cocktails waitresses.
