Democratic Rep. Gwen Moore has shoveled six figures from her campaign's war chest to her sister since 2021, filings show.

The Wisconsin congresswoman paid her sister, Brenda Moore, $113,798 from her committee throughout the midterm election cycle, according to Federal Election Commission records reviewed by Fox News Digital. Moore first added her sister as a campaign staffer during her 2004 inaugural campaign and has since paid her nearly $830,000 in donor cash, her filings show. 

The low-key Democrat represents the Badger State's heavily Democratic 4th congressional district, which includes nearly all of Milwaukee and some of its suburbs. She has not faced a threat to her House seat since entering Congress in 2005.

During the 2022 elections, Moore defeated her Republican opponent by over 50 percentage points. Moore also has not faced a Democratic primary challenger since 2018, but even when she did, she easily won by 78 percentage points. 

Politicians are allowed to add family members to their campaign payrolls. While it is legal to do so, ethics experts have generally disapproved of the practice. Despite this, both political parties have taken advantage of the perk.

Moore, whose campaign did not respond to a Fox News Digital request for comment, is not the only congressional Democrat to pay family during the midterm election cycle.

California Rep. Maxine Waters continued paying her daughter, Karen, to run her lucrative slate mailer operation, which involves other politicians paying Waters' committee to appear on endorsement mailers sent to constituents in the Los Angeles area. Waters pushed $192,000 to her daughter for the operation during the 2022 election.
