U.S. President Donald Trump, a vocal critic of the 2015 deal with world powers to lift some sanctions on Iran in exchange for curbs on its nuclear program, has taken a hard line on Tehran since he took office in January.
His administration has accused Iran of stoking unrest across the Middle East by supporting terrorist groups in Iraq, Syria, Yemen, and Lebanon.
