Gingrich endorses Trump's nuclear arms buildup

Speaking to Chris Wallace on “Fox News Sunday,” Gingrich said Trump’s statements reflected the reality of a world where Russia, China, North Korea and Iran have attempted to build up their capabilities in recent years.

“I think for the president, the next president to say, you know, we’re going to have systematically rebuild our nuclear capability is exactly right,” Gingrich said.

“We have to candidly overmatch,” added Gingrich, who was a strong backer of Trump during the campaign.
