Cohn: Tunneling can "revolutionize" transportation

Trump's National Economic Council Director Gary Cohn told Mike Allen that tunneling can "revolutionize" transportation. "The tunneling technology today is so superior and so quick," Cohn said, adding that he thinks the U.S. needs to prepare for automated technologies, such as automated cars, to change transportation.

Why it matters: Up next on Trump's agenda after the tax overhaul is infrastructure spending, which Cohn said could top a $1 trillion price tag.
