Chuck Grassley, oldest sitting senator, laments dying in office under a Dem governor

Iowa Republican Sen. Chuck Grassley, the oldest sitting U.S. senator, lamented the possibility that a Democratic governor could appoint his successor if he were to die in office, according to video of remarks he delivered late last week.

Grassley, who celebrated his 93rd birthday on Sept. 17, is currently serving in his eighth term in the Senate -- set to expire Jan. 3, 2029.

If Grassley were to die in the next two years, the next governor of Iowa -- set to be elected this fall -- would make a temporary appointment to fill the seat until the 2028 election.
