Mary Lou Retton, who captured the attention of the nation when she won the all-around women's gymnastics competition at the 1984 Summer Olympics, remains in an intensive care unit, according to an update her daughter McKenna Kelley shared Wednesday.

"My sisters Skyla, Shayla, Emma and I would like to thank everyone for the outpouring of love and support for our Mom," Kelley wrote in an Instagram post. On Tuesday, Kelley revealed her mother has been in an ICU "over a week" with a "very rare form" of pneumonia.

Since then, financial support has poured in as Retton "continues to fight." 

As of Wednesday afternoon, a fundraiser page for the legendary Olympian has received just under $260,000 in donations. The fundraiser had a stated goal of $50,000. The page also noted that Retton does not have health insurance.

"We ask that if you could help in any way, that 1) you PRAY! and 2) if you could help us with finances for the hospital bill," Kelley wrote on the fundraising page. "ANYTHING, absolutely anything, would be so helpful for my family and my mom."
