Trump: US should have a role in choosing Iran's next leader; encourages Kurdish opposition

Trump also encouraged Iranian Kurdish forces to go on the offensive.

"I think it's wonderful that they want to do that, I'd be all for it," the president said.

When asked if the US would provide or had offered air cover, he responded, "I can't tell you that," but added that the objective for the Kurds would be "to win".

"If they're going to do that, that's good," Trump added.
