Iran’s supreme leader, Ayatollah Ali Khamenei, should be “very worried” as Washington expands its military presence in the region, President Donald Trump warned in an interview on Wednesday.
"I would say he should be very worried, yeah, he should be," Trump told the U.S. broadcaster NBC News.
"As you know, they are negotiating with us."
The comments come as Trump has ordered an ongoing mass military buildup in the region as he seeks to pressure Iran to meet him at the negotiating table.
Asked about Iranian protesters, the U.S. president said: "We've had their back."
