President Donald Trump has told Congress that US hostilities with Iran have “terminated” during an ongoing ceasefire, as he argued he did not need to meet a deadline for legislative approval of the war. By law, a US president must receive Congress’ approval within 60 days of notifying lawmakers of military action, or else cease hostilities. But in a letter to congressional leaders, Trump said he does not have to comply with that war powers act as the ceasefire agreed with Iran last month had paused the clock on any such obligation.
