President Trump says U.S.

forces will obliterate Iran's power plants if it does not reopen the Strait of Hormuz within 48 hours.

Iranian forces have shut down the strait, stopping 20 percent of the world's oil from reaching markets around the world.

President Trump said this weekend he will use ICE officers to help with the delays.
