A resolution aimed at forcing the U.S. Treasury to maintain sanctions on three Russian corporations linked to a pro-Kremlin “oligarch” fell three votes short in the U.S. Senate on January 16.

Eleven Republicans joined the Democrats present to support the resolution, but Iowa’s Senators Chuck Grassley and Joni Ernst voted with the rest of the GOP caucus to defeat the measure. Although the vote was 57-42 in favor (roll call), Senate rules require 60 votes to clear this kind of procedural hurdle.
