Pro Football Hall of Famer Brett Favre announced Tuesday during a congressional hearing in Washington that he has Parkinson’s disease.

Testifying before the House Ways and Means Committee, Favre spoke about Prevacus, a company that makes a concussion medication and received $2 million in Temporary Assistance for Needy Families funds. The famed quarterback was the largest investor in Prevacus, and text messages show he began asking state officials for help securing funding for the company in November 2018, ESPN reported.

“I also unfortunately lost an investment in a company that I thought was developing a breakthrough drug for concussions that I thought would help others,” Favre said. “I’m sure you can understand that it’s too late for me, having recently been diagnosed with Parkinson’s, but that this is also a cause that is close to my heart.”

According to the World Health Organization, Parkinson’s disease is a “brain disorder that causes problems with movement, mental health, sleep, pain, and other health problems.” There is currently no cure and it is estimated that nearly one million Americans have the disease.

Prevacus founder Jacob VanLandingham pleaded guilty to fraud in July when he admitted using Mississippi welfare money to pay off gambling and other debts, ESPN reported.

Favre, 54, has spoken out about his involvement in the Mississippi welfare case and has not been charged. He is one of more than 40 people sued by the state of Mississippi seeking repayment of TANF money, USA Today reported.

Mississippi is seeking to recoup more than $90 million, more than $5 million of which went to the University of Southern Mississippi Athletic Foundation to cover the cost of building a volleyball stadium.

Favre’s daughter started playing on the school’s volleyball team in 2017.

“I wanted to help my alma mater and benefit the community,” Favre said during the hearing. “Southern Miss introduced me to the nonprofit to see if they could help with funding. I had no idea that there was anything wrong with the way the state was funding the project, especially since it had been publicly approved by many state agencies and multiple attorneys, including the attorney general.”

“A gag order from the court prohibits the parties from discussing the details of the lawsuit,” he added. “Instead, I’m here to share what I’ve seen firsthand about how reforms are needed to stop the misdirection of TANF funds.”

So far, Favre has paid back $1.1 million he received from a nonprofit for speaking fees, but Mississippi State Auditor Shad White says the famed football star still owes nearly $730,000 in interest, USA Today reports.

During a 2018 interview, when Favre was asked how many concussions he’s suffered, Favre said he only knows of “three or four,” but he believes he’s suffered more than 1,000 concussions during his 20-season NFL career.

“If you’re having ringing in your ears, seeing stars, that’s a concussion,” Favre told the “Today” show, according to ESPN. “And if that’s a concussion, I’ve had hundreds, maybe thousands of them in my career, which is scary.”
