Troubles at aircraft maker Boeing Co. could trim about half a point from U.S. GDP in 2020 but economic growth should still come in at about 2.5 percent, said Treasury Secretary Steven Mnuchin.

Mnuchin discussed the growth outlook, plans to sign the first phase of a U.S.-China trade deal and new sanctions against Iran on Fox News Channel's "Sunday Morning Futures."

"The president's economic program is really coming together," Mnuchin said.
