After it was revealed in November 2018 that Trump had business dealings with Russia while a candidate in the 2016 election, Barrasso said, "The president is an international businessman; I’m not surprised he was doing international business." Asked whether Trump should have disclosed those business ties during the campaign, Barrasso said, "There were so many things involved in the 2016 campaign, it’s hard to point to what one thing influenced voters." Barrasso joined Trump on Thanksgiving 2019 in a surprise visit to American troops stationed at Bagram Air Base in Afghanistan. At the time, approximately 370 Wyoming National Guard soldiers were deployed in Europe and the Middle East, the most since 2009.
