GOP-led House to vote on repealing Obama's power to fight IS

The House is expected to vote Wednesday on a $602 billion defense policy bill that seeks to halt an erosion of the U.S. military's combat readiness by purchasing more weapons and forbidding further cuts in troop levels.

Among the measures the Obama administration opposes is a Republican plan to shift $18 billion in wartime spending to pay for additional ships, jet fighters, helicopters and more that the Pentagon didn't request.

To make up for the shortfall in the wartime account, Obama's successor would submit a supplemental budget to Congress in early 2017, according to Rep. Mac Thornberry, R-Texas, the plan's architect and the chairman of the House Armed Services Committee.

The House bill would block reductions in the number of active-duty troops by prohibiting the Army from falling below 480,000 active-duty soldiers and adding 7,000 service members to the Air Force and Marine Corps.

To increase oversight and accountability, Senate confirmation of the president's national security adviser would be required if the size of the National Security Council staff exceeds 100 employees, according to the amendment.
