White House national security adviser Jake Sullivan outlined a series of measures to strengthen U.S. and NATO support for Ukraine on Tuesday, as leaders of the military alliance gathered in Washington for a summit.

NATO will announce in the coming days a new military command in Germany led by a three-star general for training and equipping Ukrainian troops, and appoint a senior representative in Kyiv to deepen Ukraine's relationship with the alliance, Sullivan told a conference on the defense industry sponsored by the U.S. Chamber of Commerce.
