Sen. Mitch McConnell checked himself into a local hospital Monday night “in an abundance of caution” after experiencing “flu-like symptoms,” a spokesperson for the Kentucky Republican said Tuesday. McConnell missed Senate votes on Monday and Tuesday. A polio survivor, McConnell has had increasingly public mobility challenges, including a series of falls in recent years, and is often seen requiring assistance navigating the Capitol halls. He announced last year he would not seek reelection an eighth time. David Popp, the spokesperson, said McConnell’s “prognosis is positive” and that he remains in “regular contact with his staff and looks forward to returning to Senate business.”
