"The amendment simply seeks to take the OCO budget back down to what the Pentagon asked for," he said in Tuesday night debate.
Instead of cutting $5 billion, Mulvaney said his amendment would leave an extra $1.5 billion that the bill would give to the National Guard. That made for a $3.5 billion cut.
House Budget Committee ranking member Chris Van Hollen (D-Md.) agreed with Mulvaney, and cosponsored the amendment. "There's no reason we should be throwing money into the war accounts that don't belong there simply as an accounting scheme to avoid the cap," he said.
The amendment faced GOP opposition on Tuesday night, from Rep. Rodney Frelinghuysen (R-N.J.), who said the government has been shown to underestimate the money it needs for the OCO account.
"[D]espite having a higher overseas contingency allocation for fiscal year 2013 of $87 billion, budget execution during fiscal year 2013 has proven that that request was understated by as much as $10 billion," he noted.
But most members sided with Mulvaney, as the House passed his language in a narrow 215-206 vote. The language won the support of 38 Republicans and 177 Democrats.
Mulvaney's proposal was one of a handful that got votes Wednesday afternoon, after which members were expected to debate the last dozen or so and pass the entire bill.
Other amendments getting roll call votes were from:
— Walter Jones (R-N.C.), prohibiting the use of funds to carry out activities under the U.S.-Afghanistan Strategic Partnership. Failed 177-246.
— Doug LaMalfa (R-Calif.), prohibiting funding to pay for fines assessed against any military installation by the California Air Resources Board. Passed 235-188.
