President Donald Trump’s decision to authorize overnight strikes against Iran revived sweeping debate about a decades-old law dealing with congressional involvement in military operations. 

Some in Congress have raised concerns that Trump should have received permission from Congress before signing off on the joint U.S.-Israel strikes against Iran, citing the 1973 War Powers Act. Those lawmakers range from Senate Minority Leader Chuck Schumer (D-NY) to Reps. Thomas Massie (R-KY) and Ro Khanna (D-CA).
