Democratic lawmakers and one Republican colleague on Friday demanded answers from Secretary of State Marco Rubio and Treasury Secretary Scott Bessent about why sanctioned Russian lawmakers visited the U.S. and toured the U.S. Capitol building this week, a visit organized by Rep. Anna Paulina Luna (R-Fla.). The letter, signed by Reps. Dina Titus (D-Nev.), Brian Fitzpatrick (R-Pa.), Marcy Kaptur (D-Ohio), Mike Quigley (D-Ill.), Jim Costa (D-Calif.) and Chellie Pingree (D-Maine), called the lawmakers' visit to meet with some members of Congress and other officials "deeply concerning." "Because these individuals are subject to U.S. sanctions imposed in response to Russia's full-scale, unjustified invasion of Ukraine, their entry into the United States would have required the issuance of sanctions waivers," the letter reads.
