Who Are the United States Senators From California: What Most People Get Wrong

If you’re trying to keep track of who represents the Golden State in D.C. lately, honestly, nobody blames you for being a little confused. The last few years have been a whirlwind of appointments, special elections, and historic shifts. It feels like every time you look at the news, there’s a new name or a "Senator-elect" title floating around.

But as of right now, in early 2026, the dust has finally settled.

California’s representation in the U.S. Senate is currently held by Alex Padilla and Adam Schiff.

Both are Democrats. Both have deep roots in California politics. However, they arrived in these seats through very different paths. One was a history-making appointment who eventually won his own full term, while the other is a household name from the House of Representatives who just won one of the most expensive and watched Senate races in American history.

The Senior Senator: Alex Padilla

Alex Padilla has been in the seat since early 2021, but it’s important to remember he didn't start there by winning a general election. When Kamala Harris vacated her seat to become Vice President, Governor Gavin Newsom tapped Padilla to fill the gap.

It was a huge deal. Padilla became the first Latino senator to ever represent California.

He didn't just sit on that appointment, though. In 2022, he had to do something kinda weird—he appeared on the ballot twice. Once to finish out the last two months of Harris's original term, and once for a full six-year term of his own. He won both, obviously. Now, he’s serving a term that doesn’t expire until January 3, 2029.

Before he was heading to Washington, Padilla was California’s Secretary of State. He’s basically an engineer by trade—graduated from MIT—and he brings that "how do we fix the machine" energy to policy. He’s mostly focused on:

• Immigration reform (he chairs a key subcommittee on this).
• Climate change and protecting California’s coastline.
• Voting rights, which makes sense given his old job.

The Junior Senator: Adam Schiff

Then there’s Adam Schiff. If you’ve watched even ten minutes of cable news in the last five years, you know exactly who he is. Schiff took office on December 9, 2024, following a wild election cycle triggered by the passing of the legendary Dianne Feinstein.

Feinstein’s death in September 2023 left a massive void. Governor Newsom temporarily appointed Laphonza Butler to keep the seat warm, but Butler decided not to run for a full term. That opened the floodgates. Schiff, who had represented the Burbank area in the House for decades, jumped in and eventually defeated Republican Steve Garvey in the November 2024 election.

Like Padilla, Schiff actually took office slightly early because he was appointed to finish the final few weeks of the vacancy before his "official" full term started in January 2025. His current term runs all the way until January 3, 2031.

You probably know him as the guy who led the first impeachment trial of Donald Trump. In the Senate, he’s stayed in that lane—focusing on national security, intelligence, and "protecting democracy"—but he’s also been surprisingly vocal about California-specific issues like housing costs and water rights.

Why the "Junior" and "Senior" Labels Matter

In the Senate, seniority isn't just a polite way of saying someone has been there longer. It actually dictates who gets the better office space and, more importantly, who gets the better committee assignments.

Since Alex Padilla has been there since 2021, he is the Senior Senator. Adam Schiff, despite being older and having spent more total years in Washington (as a Congressman), is the Junior Senator because he just joined the "upper house" in late 2024.

Who are the United States senators from California representing?

It’s easy to think of these two as just "California's guys," but the sheer scale of their job is nuts. They represent nearly 40 million people. That is a larger population than the bottom 21 states combined.

When Padilla or Schiff walks onto the Senate floor, they carry a "weighted vote" in terms of economic impact that most other senators can’t touch. California is the fifth-largest economy in the world. If there’s a bill about tech, Hollywood, agriculture, or aerospace, these two are usually in the middle of the room because those industries basically live in California.

A Quick History of the Seats

To understand where we are, you have to look at where we were. For almost 30 years, California was represented by the duo of Dianne Feinstein and Barbara Boxer. They were the first pair of women to represent a state at the same time, elected in the "Year of the Woman" in 1992.

When Boxer retired, Kamala Harris took her spot. When Harris became VP, Padilla took that spot.
When Feinstein passed away, Butler held the seat briefly, and now Schiff has it.

It’s the first time in decades that California has two men in the Senate. This has actually been a bit of a talking point in state politics, as many people expected Newsom to appoint another woman to Feinstein's seat for the long haul. Instead, the voters chose Schiff.

What You Should Do Next

If you want to actually see what these guys are doing for you (or against you, depending on your leanings), you should check their voting records directly. Don't just trust the headlines.

1. Check the Congressional Record: You can see every "yea" or "nay" they cast at Congress.gov.
2. Contact their offices: If you live in California and have an issue with a federal agency (like the VA or Social Security), their "constituent services" teams are actually paid to help you. You can reach Padilla’s office at (202) 224-3553 and Schiff’s office at (202) 224-3841.
3. Monitor Committee Work: Alex Padilla is big into the Judiciary Committee, while Adam Schiff has taken spots on Judiciary and Agriculture, which is a huge deal for the Central Valley.

Knowing who represents you is the bare minimum. Watching how they vote on your tax dollars is where the real work begins.
