As Vincent Gray‘s campaign ponders whether to request extended voting hours tonight because of reported problems with machines at several polling places, Mayor Adrian Fenty is greeting voters at the 4th District MPD headquarters on Georgia Avenue NW, a Ward 4 polling place.

City Paper‘s Jason Cherkis, who’s following Fenty today, grabbed him to ask about the reported problems.

“I don’t know anything about it,” Fenty said, though he added that he is concerned. When Cherkis tried to follow up, Fenty demurred. “If you have any other questions, I’d be glad to answer them.”

Update: Fenty spokesman Sean Madigan sends along this comment about reports of voting problems. “Right now we are focused 100 percent on getting our supporters to the polls.”
