Pelosi pressed for trip records

House Republicans yesterday called on Minority Leader Nancy Pelosi to provide documentation to prove that a Washington lobbyist firm did not pay for a trip she and other Democrats took to Puerto Rico in 2001."We feel that such lingering questions undermine the integrity of the institution and we hope [the matter] will be cleared up as soon as possible," wrote Republican Reps. Patrick T. McHenry of North Carolina and Lynn Westmoreland of Georgia.
