WASHINGTON – Confronted with a rebellion of tea party-backed conservatives insistent on deeper spending cuts, House Republicans are promising to cut more than $60 billion from the budget as they draft legislation funding the government through Sept. 30.

Thursday’s announcement by Appropriations Committee Chairman Harold Rogers comes just a day after he failed to sell a smaller package of cuts in a closed-door GOP meeting.

“Our intent is to make deep but manageable cuts in nearly every area of government, leaving no stone unturned and allowing no agency or program to be held sacred,” Rogers said in a statement.

Driving the move is a promise made in last fall’s campaign to cut $100 billion from President Obama’s proposals.

The Kentucky Republican had warned only Wednesday that such cuts could lead to layoffs of FBI agents and harm to the nation’s air traffic control system. He also warned of cuts to health research, special education and Pell Grants for low-income college students. Rogers’ had earlier outlined a plan making $74 billion in cuts from Obama’s proposals.

The new version announced Thursday would produce actual savings more like $60 billion because the president’s budget asked for sizable spending increases that were never enacted.
