Rep. Thomas Massie (R-KY) has long been a critic of continued U.S. membership in NATO. He’s categorized it as an archaic institution that serves no current purpose and a waste of taxpayer money. On Tuesday, Massie introduced a bill to end the country’s membership in NATO.

“NATO is a Cold War relic. We should withdraw from NATO and use that money to defend our own country, not socialist countries,” Massie said in a press release and in social media posts. “NATO was created to counter the Soviet Union, which collapsed over thirty years ago. Since then, U.S. participation has cost taxpayers trillions of dollars and continues to risk U.S. involvement in foreign wars.”
