Desiree Rogers, the White House Social Secretary, who has come under fire for her department's handling of the State Dinner guest list incident will not testify on Capitol Hill Thursday. White House Spokesman Robert Gibbs says Rogers is a White House staff member and "based on separation of powers staff here don't go to testify in front of Congress."

Ms. Rogers has been asked to brief members of the House Homeland Security Committee Thursday about how Michaele and Tareq Salahi managed to enter White House grounds for a State Dinner they were not invited to attend.  The ranking member of the Homeland Security Committee, Congressman Peter King (R-NY) told Fox News Ms. Rogers decision not to testify is "indefensible."

Gibbs would not answer repeated questions at Wednesday press briefings about whether Rogers was an invited dinner guest of the Obama's or if she "invited herself" to the party.  Typically White House social secretaries arrange the guest list and oversee the lavish and detailed dinners.  Ms. Rogers was listed as a guest and walked the red carpet to the dinner in an expensive designer dress.  Gibbs says the "first family is quite pleased with her performance."
