Treasury Secretary Steve Mnuchin said Sunday that increased tensions with Iran show that the Trump administration's approach to pressuring Tehran with sanctions is working.

"Tensions are worse because it's working," Mnuchin said Sunday on CNN's "State of the Union."

"We've cut off all the money to Iran, you see Iran in desperation attacking its neighbors," he added.

"Assume everybody attached to the U.S. dollar will abide by these sanctions," Mnuchin said.
