The sports network owned in part by the Washington Nationals is promoting a crowdfunding campaign to pay for a team executive’s leukemia treatment, and it has some fans wondering why the billionaire owner isn’t helping to foot the bill.

Doug Harris is an assistant general manager and vice president for the Washington Nationals. He has been with the organization for nearly nine years. In 2015, Harris was diagnosed with leukemia. Previously treated with a bone marrow transplant, the illness did not entirely subside, according to the GoFundMe page launched by his wife. It seeks $400,000 for a treatment called CAR-T cell therapy, which is not covered under medical insurance, per MASN Sports.

“Doug has been a beloved member of our organization for almost nine years,” the team said in a statement. “He has been instrumental in the success of our ball club, working with our players from the day they join our organization to the day they step onto the major league field. From the moment we learned of his initial diagnosis three years ago, we have supported him and his family and will continue to do so.”

The Hagerstown Suns, a minor league affiliate of the Nationals, sent a tweet asking fans to donate via GoFundMe.

But after MASN published the story about Harris’ crowdfunding campaign, there were Nats enthusiasts questioning why the team’s support—specifically that of its ownership—has not extended to footing the bill.

Dear Nationals owners,

you can and should cover these medical costs. please do it

sincerely,

every one of your team’s fans https://t.co/M8UXAi1vNv

The guy who owns the Nationals is worth $5.2 billion. DC taxpayers paid $670M of the $701M it cost to build Nationals Stadium.

Did you really think this was going to play as “heartwarming” or “appropriate” by asking fans (many who can’t afford to go to a game) to co-fund medical treatments?

So a team run by billionaires playing in a stadium the taxpayers built wants its fans to help pay for the healthcare of its employees?

Did the @NationalsPR department really think this one through? #Nats

The Lerner family owns the Nationals and has received support from the city in building Nationals Park.

Patriarch Ted Lerner and his family have a net worth of approximately $5.2 billion, making him the richest person in Maryland, according to Forbes. He transferred voting power with Major League Baseball to his son, Mark, in June.

The city contributed $670.3 million of the $701.3 million it cost to build Nationals Park, according to a 2008 estimate. Despite $80 million of that taxpayer money going toward upgrades to the Navy Yard Metro station, the Lerners have repeatedly declined to pay for extended train service during late-night postseason games.

The Nationals’ payroll on opening day 2018 was estimated at approximately $180 million by USA Today, making it the fourth largest in the league and the highest ever for the team, per MASN.

The Nationals have not responded to a request for comment about fans asking why the Lerner family isn’t covering the costs.

Harris isn’t the only one to turn to crowdfunding to finance medical bills. Nearly half of the $2 billion raised on GoFundMe from 2010-early 2016 was for health-related campaigns. So far, the Harris fundraiser has raised almost $58,000 from 414 people.
