Sen. Mitch McConnell, R-Ky., was hospitalized for an undisclosed health issue, according to his office.
"Sen. McConnell was admitted to the hospital this morning," McConnell's Communications Director David Popp told Fox News. "He is receiving excellent care."
McConnell, the longest-serving Senate party leader in U.S. history, was previously hospitalized for eight days earlier this year after experiencing "flu-like symptoms."

The 84-year-old senator announced last February that he would not seek reelection and would retire when his current term ends in January 2027.
McConnell has dealt with a series of health episodes in recent years, including injuries from falls and multiple instances in which he briefly froze while speaking publicly.
Only Sen. Chuck Grassley, R-Iowa, at 92 and Sen. Bernie Sanders, I-Vt., at 84, are older than McConnell in Congress.
