Tyrone Gayle, Senator Kamala Harris’ press secretary, died of colon cancer on Thursday.

The sad news was announced by Ian Sams, communications director for Senator Tim Kaine, on Twitter.

Gayle was diagnosed with the disease in 2016 and spent 21 days in the hospital, according to Anderson Independent Mail.

He began working for Harris in January 2017. The California senator called Gayle “irreplaceable” in a statement.

Before his work with Harris, the 30-year-old worked for Hillary Clinton’s second presidential campaign and Tim Kaine’s 2011 Senate campaign, where he met his wife, according to The New York Times.

“All who crossed Tyrone’s path were affected by his warmth, humor and positive energy,” Kaine said in a Facebook post.

The senator from Virginia also reminisced about Gayle's wedding.

“It was one of the honors of my life to officiate at Tyrone’s wedding to Beth just six months ago," Kaine wrote. "And I preached about the unusual repetition in a line in the Lord’s Prayer: 'Give us this day our daily bread.' Not enough for all time, just enough for today. And Tyrone lived — and shared — a life of many beautiful todays.”

Clinton also paid tribute to Gayle via her Twitter page.

Jesse Lehrich, a former Clinton spokesman, has launched a memorial fund for his wife, Beth Foster.
