Russia on Sunday claimed its troops had captured a strategically important town in eastern Ukraine, as part of a grinding campaign to weaken Kyiv’s grip on the country’s industrial heartland.

Russia’s aggression in Ukraine has been a splitting point between Trump and the more hawkish Republican Senate conference. Last year, Trump blew up a deal to swap additional provisions for border security in exchange for aid to Israel and Ukraine. Aid to Ukraine ultimately passed without additional border security spending.

Russia says it shot down more than 120 drones overnight, in what would be one of the largest attacks of the war.
