On Friday, Vice President Mike Pence will lead a delegation of Trump administration officials to Germany for the annual Munich Security Conference, and his first trip abroad is expected to focus on reassuring allies nervous about President Trump's comments and actions. Trump's shifting position on NATO, support for Britain's EU exit, perceived closeness to Russia, and "America First" mantra have raised "an unbelievable number of questions," says Wolfgang Ischinger, a conference organizer. Other members of Pence's entourage include Defense Secretary Jim Mattis and Homeland Security Secretary John Kelly, and there is a separate U.S. congressional delegation. Pence will speak at the conference on Saturday, along with German Chancellor Angela Merkel, then meet with European leaders on Sunday and Monday; they will be trying to gain insight into what Trump wants, and how much influence Pence has over the U.S. president.
