Their motivations remain a total mystery.
Via Weekly Standard:
The $831,000,000,000 economic “stimulus” that President Obama spearheaded and signed into law requires his administration to release quarterly reports on its effects. But “the most transparent administration in the history of our country” is now four reports behind schedule and has so far not released any reports whatsoever in 2012. Its most recent quarterly report is for the quarter than ended on June 30, 2011. [...]
Section 1513 of the American Recovery and Reinvestment Act of 2009 (the “stimulus”) explicitly states, “In consultation with the Director of the Office of Management and Budget and the Secretary of the Treasury, the Chairperson of the Council of Economic Advisers shall submit quarterly reports to the Committees on Appropriations of the Senate and House of Representatives that detail the impact of programs funded through covered funds on employment, estimated economic growth, and other key economic indicators.” (The head of the Council of Economic Advisors, currently Alan Krueger, is appointed by the president, confirmed by the Senate, and works within the Executive Office of the President. He is the president’s chief economic adviser.)
