The chamber voted to repeal both AUMFs by a bipartisan 66–30 vote Wed..

What do AUMFs do? AUMFs give the president power to use military force without congressional approval. (Axios)

Congress first passed an AUMF in 1991 during the Gulf War; Congress also passed AUMFs in 2001 and 2002 in wake of 9/11.

What did the 1991 AUMF do? It allowed then-Pres. H. W. Bush to deploy troops in response to Iraq's invasion of Kuwait. (AP)

In 2002, Congress passed an AUMF to allow then-Pres. W. Bush to invade Iraq and remove Iraqi Pres. Saddam Hussein. (AP)

Both AUMFs have been in effect since their enactment: both Trump and Obama used the 2002 AUMF to authorize military action.

Senate Majority Leader Chuck Schumer celebrated the bill's passage Wed.: "I hope this process can be a blueprint."

Will the bill pass the House? According to CNN, House Speaker Kevin McCarthy supports the AUMF repeal.

Pres. Biden voiced his support for the AUMF repeal in March: "...the Administration supports Senate passage of S. 316."
