You’ve probably heard the term "President pro tempore" tossed around during C-SPAN broadcasts or late-night news cycles. It sounds fancy. It sounds like something out of a Latin textbook. But in the actual, day-to-day grit of Washington D.C., the role is both a massive honor and a bit of a logistical powerhouse.
Right now, Chuck Grassley is the current pro tempore of the senate.
The Iowa Republican took the gavel back on January 3, 2025, when the 119th Congress kicked off. If you’re keeping track, this isn't his first rodeo. He held the exact same job from 2019 to 2021. He’s basically the Senate’s institutional memory at this point.
Who is Chuck Grassley?
Chuck Grassley isn’t just some guy in a suit. He’s 92 years old. That makes him the oldest sitting member of the Senate. He’s been representing Iowa since 1981, which is a staggering amount of time when you think about how much the world has changed since then.

He succeeded Patty Murray, the Democrat from Washington who made history as the first woman to hold the position. When the Senate majority flipped back to the Republicans, the tradition of "seniority" took over.
See, the Senate is obsessed with tradition. The President pro tempore (which literally means "President for the time being") is almost always the longest-serving member of the majority party. It’s not a job you campaign for. You earn it by staying in office longer than everyone else on your side of the aisle.
What does the current pro tempore of the senate actually do?
Most people think this is just a ceremonial role where you sit in a big chair and look important. That’s partially true. But the Constitution actually requires this office.
- Presiding over the Senate: When the Vice President (who is the official President of the Senate) is busy—which is basically always—the pro tempore is the boss of the floor.
- The Line of Succession: This is the big one. Chuck Grassley is currently third in line for the presidency. If something happens to the President, the Vice President, and the Speaker of the House, the keys to the White House go to him.
- Signing Bills: Before a bill reaches the President’s desk to become law, the pro tempore has to sign it.
- Oaths of Office: He’s the one who swears in new senators or officers.
Honestly, it’s a lot of paperwork.
The Politics Behind the Position
While the title is constitutional, the day-to-day work is often delegated. You won’t usually see Grassley sitting in that presiding chair for twelve hours straight. Instead, he often appoints junior senators to do the heavy lifting. It’s like a training ground for the "newbies" to learn how the Senate’s complex rules actually work.
In 2026, the political landscape is pretty divided. Having a veteran like Grassley in this spot provides a kind of "old school" stability. He’s known for his "History Committee" and his very... unique... Twitter (X) presence where he talks about deer and Dairy Queen. But in the halls of the Capitol, he's a serious player who also chairs the Senate Judiciary Committee.
Why does it matter who is the current pro tempore of the senate?
You might think, "Who cares who signs the bills as long as they get passed?"

Well, it matters for stability. If there’s ever a national crisis, knowing exactly who is in that line of succession is vital. Plus, the pro tempore has a say in appointing people to various national commissions and boards. They aren't just a figurehead; they are a gatekeeper for a lot of the quiet machinery that keeps the government running.
Realities of the 119th Congress
The transition from Patty Murray to Chuck Grassley was a clear signal of the shift in power. While Murray’s tenure was historic for gender representation, Grassley’s return is a return to a specific kind of Senate institutionalism.
He’s the second Iowan to ever hold the job. The first was Albert B. Cummins back in 1919. It’s a rare feat.
One thing to keep an eye on is the "Acting" President pro tempore. Because the job is demanding, you’ll often see names like Pete Ricketts or other Republicans filling in. They are doing the work, but Grassley holds the constitutional authority.
Actionable Steps for Staying Informed:
- Follow the Senate Daily Digest: If you want to see what Grassley is actually signing or presiding over, the Congressional Record is public. It's dry, but it's the only way to get the facts without the spin.
- Watch the Line of Succession: Always be aware of the top four: the President, Vice President (JD Vance), Speaker of the House (Mike Johnson), and the President Pro Tempore (Chuck Grassley).
- Track Seniority: If you want to know who is next in line for this role in future Congresses, look at the seniority lists for both parties. It’s almost always predictable based on years of service.
Understanding the role of the current pro tempore of the senate helps you see past the headlines and into the actual structure of American power. It’s a mix of ancient tradition and very real, modern responsibility.
