The House passed a $1.9 trillion spending bill Friday that includes a $4 trillion defense bill, an $816 billion defense spending bill and a $3.9 billion Medicare prescription drug benefit package.
But Republicans say they will not support the package, citing the way it funds military programs and the funding for veterans.
The vote on Friday marked the second time Republicans have failed to reach agreement on a military spending bill since the Sept. 11, 2001, terrorist attacks.
And Republicans have been split over the way they are expected to vote on the military bill.
One of the major sticking points is the military funding bill, which has been described as too large.
The bill calls for a new $6.5 trillion in spending for the Pentagon, including $6 trillion for weapons systems, according to The Associated Press.
But the GOP-controlled House is also planning to raise the Pentagon’s spending for next year to $18.5 billion.
The Senate is expected to pass the bill as well.
Democrats are also expected to approve the bill on Friday.
