Colorado U.S. Sen. Michael Bennet is calling on Congress to debate and pass a new authorization for military operations, citing the ever-changing nature of security threats.

“The current authorizations for the use of military force are not reflective of today’s security environment,” Bennet said Friday in a statement. “Congress must exercise its authority and have a robust rebate on our ongoing wars.

“We owe it to our men and women who continue to lay their lives on the line in service to our country.”

This week Bennet, a Democrat, voted to repeal the 2001 and 2002 authorizations for the use of military force (AUMF) in an effort to trigger a Congressional debate that would lead to the passage of a new one.

Some have argued that the current authorizations, created in the wake of the Sept. 11, 2001, attack, grant the president too broad of an authority to commit troops overseas.

Bennet called on the Senate Foreign Relations Committee to take up a bipartisan AUMF like the one Sens. Flake, R-Ariz., and Kaine, D-Minn., put forward.
