A bi-partisan group of senators will attend next week’s NATO summit in Lithuania in a show of support for Ukraine. Russia’ war in Ukraine is expected to be a major focus at the annual conference. The U.S. senate delegation will be headed by Democrat Jeanne Shaheen [D-NH] and Republican Thom Tillis [R-NC]. In a joint letter they write their trip is meant to send what they call a “resounding message” to the international community about U.S support for the alliance amid shared security challenges.
