Montana Republican Representative Ryan Zinke announced on Monday that he will not seek reelection, marking the latest in a wave of GOP retirements ahead of a potentially challenging midterm election. Zinke, who has represented Montana since 2015 with a break to serve as Secretary of the Interior under President Trump from 2017 to 2019, cited ongoing health issues stemming from his time as a Navy SEAL as the primary reason for his departure. He explained that he faces further surgeries and a significant recovery period, which he believes will prevent him from fulfilling his voting duties in Congress. This decision adds to the more than 30 House Republicans who have already announced their retirements.
