Lawmakers are calling on the administration to share U.S. intelligence with Ukraine about Russian troops massed on the country's eastern border, in order to help Ukrainian forces defend themselves against an invasion.
On Tuesday, Reps. Buck McKeon (R-Calif.), Mike Turner (R-Ohio) and Mike Rogers (R-Ala.) called on the administration to provide Ukrainian forces with U.S. intelligence, military advice and technical support.
According to Turner, NATO Supreme Allied Commander Europe Gen. Philip Breedlove has identified 80,000 Russian troops along the Ukraine border, that are part of an "invasion-ready force" that includes field hospitals.
Schiff acknowledged U.S. officials were concerned that shared intelligence would end up in the hands of Russian intelligence agencies, and said "we have to be careful what we share that doesn't disclose sources and methods of our intelligence gathering."
