President Trump had pledged to use his relationship with Russian President Vladimir Putin to broker a deal. But he's been vague about potential outcomes from his Friday summit.

Anchorage, Alaska — U.S. President Donald Trump is meeting face-to-face with Russian President Vladimir Putin in Alaska on Friday for a high-stakes summit that could determine not only the trajectory of the war in Ukraine but also the fate of European security.

U.S. allies are hopeful they have steered the president away from a potential Putin diplomatic trap, diplomats and former U.S. officials told NBC News.
