WASHINGTON (Reuters) - U.S. Secretary of State Mike Pompeo on Wednesday said the United States would be open to extending the New START nuclear arms control treaty beyond its expiration in February based on understandings reached in recent talks with Russia. “We would welcome the opportunity to complete an agreement based on the understandings that were achieved over the last couple of weeks about what the range of possibilities look like for an extension of New START,” Pompeo told a State Department news conference.
