The president is threatening escalation with Iran, warning that whenever Iran fires at a ship in the Strait of Hormuz, "The United States will bomb and destroy ONE BRIDGE OR POWER PLANT, including those located next to, or in, the Capital City of Tehran."

Iran continued to fire at countries in the region, while its foreign minister warned "Any aggression against Iran, including our infrastructure, will compel a powerful and decisive response."

"We remain open to working it out in a negotiated way. But right now, they don’t seem to be serious about that. And so we’re going to continue to protect shipping," said Secretary of State Marco Rubio.
