Obama Again Huddles with Vice Presidential Vetter

By Jonathan Weisman
For the second straight day, Sen. Barack Obama spent hours huddled behind closed doors in the office of vice presidential vetter Eric Holder, stoking speculation that he is closing in on a running mate.

Obama was in Holder's office for nearly three hours this afternoon. He then sped off a few minutes late for a 5:30 date with House Democrats on Capitol Hill.

Obama said nothing as he left the building.
