Senator Chuck Grassley, the oldest member of the U.S. Senate, marked his 93rd birthday on September 17 while continuing to actively fulfill his duties in Washington. Known for his distinctive style of brief social media updates and his fondness for Dairy Queen Blizzards, Grassley celebrated the occasion with a Dairy Queen ice cream cake in his Capitol office.
The Iowa Republican began the day with his routine two-mile walk, a daily habit he maintains despite no longer running as he once did. When asked about his longevity in office, Grassley responded with humor, noting his age and family milestones, underscoring his continued engagement in Senate business.
Grassley’s birthday highlights a broader national conversation about the age and health of elected officials. While concern is growing among the public regarding officials’ advanced age, no federal age limit exists for Congress. Data shows Grassley is among several senior lawmakers, including Representative Hal Rogers of Kentucky, 88, and Delegate Eleanor Holmes Norton of Washington, D.C., 89. Senator Mitch McConnell, 84, also drew attention recently following a brief absence fueled by questions about his health.
The current Senate's average age stands at 63.9, while House members average 57.9 years old. These statistics contrast with the U.S. population’s median age of 39.4, suggesting congressional demographics do not mirror the broader populace. A recent poll indicated that about 80% of Americans support imposing a maximum age limit for congressional members, a view that crosses political affiliations.
Grassley, who began his Senate career in 1981, serves as chairman of the Senate Judiciary Committee and holds the position of president pro tempore, placing him third in the presidential line of succession. He is the sixth longest-serving senator in history and has two years left in his current term.
Despite his age, Grassley remains actively engaged in legislative work. His office reported that on September 16, he chaired a Judiciary Committee hearing, participated in a key Agriculture Committee vote on the farm bill, conducted press calls with Iowa journalists, met with constituents, and voted on the Senate floor. When in Iowa, he continues to travel statewide, holding town halls and updating followers on his farm’s operations.
Grassley has not publicly stated whether he intends to run for reelection in 2028. Should he decide to seek another term and complete it, he would be 101 years old by the end, surpassing the tenure age record set by former Senator Strom Thurmond of South Carolina.
