House Foreign Affairs Committee Chairman Ed Royce (R-Calif.), the sponsor of the bill, says this focus is needed to ensure the safety of U.S. diplomatic personnel around the world.

"While this bill is fiscally responsible — representing a nearly 9 percent overall cut in spending from last year — it fully funds the administration's embassy security request," Royce said in August. "It also contains important embassy security reforms, in response to the Benghazi attack."

Specifically, the bill authorizes $4.83 billion for embassy security, including $1.38 billion to shore up security in buildings that fall short on security, and $101 million to upgrade some facilities with blast-resistant doors and windows.

It also requires the State Department to list all high-risk and high-treat posts, and to focus on making improvements to these buildings.

In other areas, it requires State to develop contingency plans to keep government workers safe, and gives the department the flexibility to spend more on upgrades where needed instead of relying on the lowest bid from contractors. It also authorizes funding for 156 Marine Corps Security Guards at overseas posts.

The GOP will call up this bill under a suspension of House rules, which means it will need a two-thirds majority to pass.
