The White House is cooperating fully with Democratic efforts to keep the House in 2010, Speaker Nancy Pelosi (D-Calif.) said Thursday.

"There is absolutely no reason to think that the White House has been anything but cooperative with us in terms of our political efforts to retain control of the Congress," Pelosi said at her weekly press conference.

Democrats have expressed frustration with Press Secretary Robert Gibbs's comment last weekend that enough seats were in play for Republicans to take control of the lower chamber:

More broadly, some Democrats complain, the White House has not made an aggressive enough push to keep the House in Democratic hands this fall.

“It was the straw that broke the camel’s back,” one Democratic campaign strategist working on 2010 elections said of Gibbs’s comments.

Lawmakers in the lower chamber have taken note that the president has held many more fundraising and campaign events for Senate candidates than House candidates. During the recent July 4 recess alone, one campaign aide pointed out, the president stumped for two Senate candidates — Majority Leader Harry Reid in Nevada and Robin Carnahan in Missouri — but did nothing for House candidates.
