When was the Union's Joint Committee on the Conduct of the War created?

Radical Republicans who were dissatisfied by the way the Lincoln administration was pursuing the Union's war efforts formed the Congressional Joint Committee on the Conduct of the War. This committee was formed in December of 1861. The Committee's investigations on the Union's war efforts caused fury and controversy throughout the the war. It impacted, for example, Lincoln's selection of political appointees to generalships.
