The White House Tuesday said that President Obama will not endorse District of Columbia Mayor Adrian Fenty (D), who faces a tough primary challenge from D.C. City Council Chairman Vincent Gray (D).

Fenty reportedly asked for Obama's endorsement last week, but none will be coming as voters head to the polls to choose a nominee on Tuesday.

"There are seven states today that are having primaries, and probably hundreds of different races all around the country. You could ask the same thing about any one of those," White House deputy press secretary Bill Burton told reporters aboard Air Force One. "The president doesn’t get involved in every single race, and didn’t get involved in a lot of them today."

Recent polls show Gray leading Fenty, who endorsed Obama for president during the 2008 election campaign.

Asked if the president wants Fenty to win, Burton said, "I haven’t talked to him about the race specifically."
