WASHINGTON — Retired NFL quarterback Brett Favre has been diagnosed with Parkinson’s disease, he told a congressional committee Tuesday.

Favre made the disclosure as part of his testimony about a welfare misspending scandal in Mississippi. Favre, who does not face criminal charges, has repaid just over $1 million in speaking fees funded by a welfare program in the state and was also an investor in a biotech company with ties to the case. The biotech firm has said it was developing concussion treatments.

The former football star told the committee that he lost his investment in the company ”that I believed was developing a breakthrough concussion drug I thought would help others.”

”As I’m sure you’ll understand, while it’s too late for me — I’ve recently been diagnosed with Parkinson’s — this is also a cause dear to my heart,” Favre said.

What causes Parkinson’s disease is unknown, and it is unclear if Favre’s disease is connected to his football career or head injuries. He said in 2022 that he estimates he experienced ”thousands” of concussions in his two decades in the NFL.

Favre appeared at the Republican-led House Ways and Means Committee hearing to advocate reform of the federal welfare system to better prevent fraud.

”The challenges my family and I have faced over the last three years—because certain government officials in Mississippi failed to protect federal TANF funds from fraud and abuse, and are unjustifiably trying to blame me, those challenges have hurt my good name and are worse than anything I faced in football,” Favre said.

House Republicans have said a Mississippi welfare misspending scandal involving Favre and others points to the need for an overhaul in the federal Temporary Assistance for Needy Families program.
