S. 3491 would authorize the appropriation of $2 million in 2022 to establish a new legislative branch commission. The commission, comprising eight members chosen by the Congress, would have 18 months to examine the challenges of modern-day diplomacy and report to the President and the Congress on its findings. It also would make recommendations on ways to improve the operations and management of the Department of State. CBO estimates that implementing the bill would cost less than $500,000 in 2022 and a total of $2 million over the 2022-2026 period, subject to the appropriation of the specified amounts.
