An amendment that would add the National Guard chief to the Joint Chiefs of Staff was tacked onto the Defense authorization bill Monday evening.
The amendment, which was sponsored by Sens. Patrick Leahy (D-Vt.) and Lindsey Graham (R-S.C.), passed in the Senate on a voice vote.
The amendment, if passed into law, would make the Guard head a member of the Joint Chiefs of Staff. A similar provision was included in the House version of the Defense authorization bill.
Joint Chiefs Chairman Gen. Martin Dempsey is opposed to adding the Guard chief. Dempsey, the vice chairman and the service chiefs testified at the Senate Armed Services committee earlier this month urging senators to vote against the plan.
Dempsey said that the Guard chief already sits in for meetings, and that the Guard head does not have the same budget authority as the other service chiefs.
The Guard amendment was one of more than 100 that are included in the Defense authorization bill, which the Senate is considering this week. Senate Armed Services Chairman Carl Levin (D-Mich.) said they hope to have a final vote by Thursday.
