John Anthony Barrasso III is the Senate Majority Whip for the 119th Congress, making him the second-most powerful Republican in the United States Senate. An orthopedic surgeon by training, Barrasso has represented Wyoming since 2007. Following Mitch McConnell's retirement from leadership, Barrasso decisively won the Whip position, acting as Majority Leader John Thune’s primary vote counter and enforcer. Barrasso is the Senate's leading voice on energy policy and deregulation. He also serves as the Chairman of the Senate Energy and Natural Resources Committee, a dual role that gives him immense power over the Trump administration's "drill baby drill" mandate. He is fiercely dedicated to dismantling the Biden-era environmental regulations, expanding federal land leasing for oil and gas extraction, and accelerating the permitting process for new energy infrastructure.
