California Attorney General Kamala Harris speaks onstage during Children’s Defense Fund – California Hosts 24th Annual Beat The Odds Awards at Book Bindery on December 4, 2014 in Culver City, California.

*California Attorney General Kamala Harris is running to replace retiring U.S. Sen. Barbara Boxer, and the Democrat has turned to her longtime supporter Jamie Foxx for a new fundraising email.

“I joined team Kamala early on because I knew then what I still know to this day,” Foxx wrote in the message, obtained by The Hill.

The Oscar winner’s letter goes on explain why folks should open up their wallets for the cause.

“She’s smart, has integrity and is committed to making Californians’ lives better,” he continued. “If we’re serious about having a senator who’s going to fight for us, we’ve got to reach into our pockets and make it rain for this campaign.”

Foxx says that Harris has the legal background needed to be a senator.

“We want a senator who’s going to stand up for all of us — one who’s got experience fighting for safer communities, a healthier environment and more opportunities for every hardworking family,” he said.

“That’s my friend Kamala. I’ve been supporting her for years — ever since she was San Francisco District Attorney, running for Attorney General of California.”

Harris is facing competition from fellow Democrat Rep. Loretta Sanchez, who announced her own candidacy in May.

Harris revealed last month that she was overhauling her campaign staff amid concerns she is overspending before the June primary. The Hill recently reported that Harris has used her campaign account to fund luxury hotel stays and first-class airfare. A Dec. 9 review by The Hill concluded she had made such purchases repeatedly during her nearly five-year tenure as California’s attorney general.

Meanwhile, Foxx joins a number of celebs who are stumping for Harris Federal Election Commission records show that John Legend, Sean Penn and Facebook chief operating officer Sheryl Sandberg are among her contributors.
