Pence warns that Putin will attack a NATO nation if he overruns Ukraine | National-politics [Video]

(CNN) — Former Vice President Mike Pence on Thursday warned that if Russian President Vladimir Putin were to “overrun” Ukraine, he would then attack a NATO nation, forcing the US to become directly involved.

“I have no doubt in my mind having met Vladimir Putin that if Putin were allowed to overrun Ukraine, it would not be long before he crossed the border of a NATO country where our men and women in uniform would be required to fight,” he told CNN’s Jake Tapper in an interview on “The Lead.”
