U.S. Senate candidate Loretta Sanchez says she's "disappointed" that President Obama has endorsed her rival Kamala Harris.
In a statement Tuesday, Sanchez said she would think that Obama would be focusing on defeating Republican presidential nominee Donald Trump and GOP Senate candidates.
Sanchez took aim at what she called the "same political establishment" that she says would rather have a "coronation instead of an election for California's next U.S. Senator."
"California's Senate seat does not belong to the political establishment — it belongs to the People of California, and I believe California voters will make their own independent choice for U.S. Senate in November," she stated in a news release.
Sanchez, a 10-term congresswoman, and Harris, state attorney general, face off in the November general election to succeed outgoing California senator Barbara Boxer.
Obama and Vice President Joe Biden both announced their endorsement of Harris on Tuesday.
Sanchez has been waging an uphill battle against front-runner Harris, who has a significant lead in both the polls and fundraising. A recent Field Poll showed Harris leading Sanchez 39 percent to 24 percent.
