Boehner, R-Ohio, says the sequester was all Obama's idea in the 2011 negotiations that produced it, but the House speaker hasn't committed to an effort to block the spending cuts before they strike.
Sen. Barbara Mikulski, D-Md., chairwoman of the Senate Appropriations Committee, praised the administration for releasing "compelling information" on the impact of the spending cuts.
"The impacts of sequester are devastating to the American people and the American economy. The public has a right to understand how sequester would impact middle-class families, jobs and the economy," she said in a statement.
