Republican, former Olympian and Keeping Up With the Kardashians cast member Caitlyn Jenner—who wants to unseat Democrat Gavin Newsom and become the next governor of California—just committed another PR blunder on the campaign trail.

After several attacks against Governor Newsom failed to garner her more than 6% support among California voters, Jenner set her sights on a new target: California's First Lady Jennifer Siebel Newsom.

Jenner's recent online faux pas adds to the list of campaign flubs. She tweeted a clear misunderstanding of California election rules, a Marie Antoinette moment about high-speed rail, pointed attacks on young trans athletes, proposed a commission to judge which underage girls are "really trans" and started a feud with late night host Jimmy Kimmel.

Now Jenner is attacking Jennifer Siebel Newsom, Queerty reported.

In a tweet, Jenner called out Siebel Newsom for an annual salary of $300,000 as director of The Representation Project. The organization is a global non-profit formed in 2011 "to fight sexism through films, education, research and activism."

The organization was created after the documentary film Siebel Newsom wrote, directed and produced, Miss Representation. The documentary garnered mostly positive reviews at Sundance and other film festivals.

For all her pearl-clutching, Jenner, a vocal supporter of Donald Trump, is worth an estimated $100 million dollars. Jenner was born in upstate New York to an upper middle-class family then made her own fortune through endorsements, speaking engagements after her Olympic gold medal win in 1976 and the lucrative years spent on reality TV.

Nonetheless, Jenner tore into Stanford University MBA graduate Siebel Newsom for her salary.

"Gavin's wife makes nearly 300k/year through her 'nonprofit' funded by her husband's lobbyist pals. As is commonplace with his administration, this stinks of corruption. Add this to the long laundry list of reasons to kick him out of office. #RecallGavin"

People who saw Jenner's tweet were not shy with their criticisms.

They were happy to call out the hypocrisy when they saw it.

Given Jenner's family has dominated tabloids for the better part of the last decade or so, there's no knowing just where this feud could end if Newsom fires back.

Of course, only time will tell what new dynamics the race takes on.

One thing, however, is for sure. Like her favorite President, Jenner will be all over Twitter slinging mud throughout the whole thing.
