After Lindsey Graham's death, sister joins long list of relatives who replaced late family members in Congress

Following the sudden death of Sen. Lindsey Graham, R-S.C., Republican South Carolina Gov. Henry McMaster appointed Graham's younger sister, Darline Graham, to fill his seat for the remainder of his term, continuing a legacy of family members stepping in to take the reins of power from their kin.

When Darline is sworn in Tuesday afternoon, she will become the latest example of a U.S. lawmaker sliding into a seat vacated by a deceased family member.

Rep. Julia Letlow, R-La., is a favorite of President Donald Trump and has his backing in her ongoing campaign to represent Louisiana in the U.S. Senate.

Her political career began years ago when Julia's husband, Luke Letlow, died from COVID-19 complications in December 2020, just over a month after residents of Louisiana's 5th district had voted him in as their congressman.

Though Luke Letlow was never sworn into office, his widow picked up the torch, running in and winning the 2021 special election to fill the House seat.

On the other side of the aisle, Rep. Adelita Grijalva, D-Ariz., was also thrust into the halls of Congress after tragedy struck her loved one.

Grijalva's father, former Rep. Raúl Grijalva, D-Ariz., died of lung cancer in March 2025. Raúl had already announced that he would not be seeking re-election after a 22-year stint in Congress.

Six months later, Adelita Grijalva won a special election for her father's seat, defeating Republican candidate Daniel Butierez Sr. by more than 40,000 votes, according to results published by the Arizona secretary of state.

TRUMP REVEALS WHO HE'S EYEING TO REPLACE LINDSEY GRAHAM

Though Democrats cried foul when House Speaker Mike Johnson, R-La., initially delayed her swearing in, she officially became a member of the U.S. House of Representatives on Nov. 12, 2025.

Former Rep. Erica Lee Carter, D-Texas, also ascended into Congress as the result of a parent's death.

Carter's mother, Rep. Sheila Jackson Lee, D-Texas, was a progressive stalwart as the representative from Texas' 18th Congressional District, which includes parts of Houston, from 1995 until her 2024 death.

Though Jackson Lee won the Democratic primary for the 2024 election in March 2024, she died of pancreatic cancer just four months later.

The Democratic Party, including Erica Lee Carter, initially rallied around former Houston Mayor Sylvester Turner to replace Jackson Lee in a November special election. But shortly after endorsing Turner, Lee Carter changed her mind and decided to run to complete her mother's term. Turner dropped out, and Lee Carter won the election by nearly 100,000 votes, according to results published by the Texas secretary of state.

Lee Carter chose not to run for re-election, finishing her mother's term in January 2025 and choosing to cede the party's nomination for the seat to Turner.

Though Turner won the seat and was sworn in Jan. 3, 2025, he served for two months, dying of bone cancer in March.

Arguably the most famous example of a spouse stepping in for a deceased partner is the tale of Sonny Bono, who for years toured the U.S. with his then-wife, pop icon Cher, as one half of the iconic musical duo Sonny and Cher.

Bono and Cher would eventually divorce and, after marrying and divorcing a third wife, Bono wed his fourth and final spouse, Mary Whitaker, in 1986.

Sonny ran for U.S. Congress as a Republican in 1994, winning a seat as the representative for California's 44th district.

But when Bono died in a skiing accident in 1998, his wife, then known as Mary Bono, ran in a special election to fill his seat. Mary Bono ended up serving 15 years in Congress, losing her seat to Democratic challenger Raul Ruiz in 2013 after her district was redrawn.

In New Jersey, former Rep. Donald Payne Jr., D-N.J., replaced his father, former Rep. Donald Payne Sr., D-N.J., in Congress.

Payne Sr. had represented New Jersey's 10th district for 23 years, a tenure that was cut short when he succumbed to a fight with colon cancer in March 2012.

Donald Payne Jr. ran in the special election to replace his father and won.

McMaster's decision to tap Darline Graham to replace her brother will make her the first female U.S. senator in South Carolina history.

When their parents died in 1976 and 1977, Lindsey became his sister's legal guardian. Accepting McMaster's nomination for her to replace her brother, Darline vowed to return the favor of his lifetime of taking care of her.

"Lindsey has always been there for me. And, now, I will be there for him," she told a crowd at South Carolina's statehouse in Columbia, South Carolina, Monday.
