(CNSNews.com) – When Rep. Nancy Pelosi (D-Calif.) gave her inaugural address as speaker of the House in 2007, she vowed there would be “no new deficit spending.” Since that day, the national debt has increased by $5 trillion, according to the U.S. Treasury Department. “After years of historic deficits, this 110th Congress will commit itself to a higher standard: Pay as you go, no new deficit spending,” Pelosi said in her speech from the speaker’s podium. “Our new America will provide unlimited opportunity for future generations, not burden them with mountains of debt.” Pelosi has served as speaker in the 110th and 111th Congresses. At the close of business on Jan. 4, 2007, Pelosi’s first day as speaker, the national debt was $8,670,596,242,973.04 (8.67 trillion), according to the Bureau of the Public Debt, a division of the U.S. Treasury Department. At the close of business on Oct. 22, it stood at $13,667,983,325,978.31 (13.67 trillion), an increase of 4,997,387,083,005.27 (or approximately $5 trillion). Under the U.S. Constitution, the federal government cannot spend any money that has not been approved by congressional appropriations; and, by congressional precedent, appropriations bills originate in the House. "No money shall be drawn from the Treasury, but in Consequence of Appropriations made by Law," says Article 1, Section 9, Clause 7 of the Constitution.
