WASHINGTON (CNN) - The U.S. Senate tackles a $410 billion emergency spending bill Monday aimed at keeping the federal government operating for the remainder of fiscal year 2009, which ends September 30.
President Obama is expected to sign it by Friday or the government runs out of money.
But critics say there's excessive spending in the bill, which would be contrary to the president's recent pledge to cut unnecessary government spending and pork-laden earmarks.
Banning earmarks - usually pet projects of congressional members inserted in spending bills unrelated to the projects - is one of several pledges Obama made on the campaign trail and has made as president.
Obama said in his weekly address Sunday that politicians will "have to be more vigilant than ever in eliminating the programs we don't need in order to make room for the investments we do need. I promised to do this."
But several of Obama's Cabinet members, who served in Congress before joining the new administration, have earmarks listed on the bill
Vice President Joe Biden requested $750,000 for a University of Delaware program during his time as the senator from that state. Obama's chief of staff Rahm Emanuel, who was a Democratic congressman from Illinois, requested $900,000 for a planetarium in Chicago.
An Emanuel aide told CNN Monday that the request was submitted more than a year ago and is leftover business.
