Some European leaders remain skeptical that President Donald Trump's emissaries actually speak for the new American leader.

Vice President Mike Pence and the U.S. secretaries of state and defense are telling European allies in person that the U.S. will steadfastly support NATO and demand that Russia honor its commitments to end fighting in Ukraine.

The president of Poland, for one, says he's waiting for action from the Trump government.

European countries along Russia's border have been rattled by the prospect of deeper U.S.-Russia ties after Trump bucked the opinions of German Chancellor Angela Merkel and other world leaders by suggesting that sanctions imposed on Russia over its intervention in Ukraine could be eased in exchange for a nuclear arms deal.
