Klete Keller made his country proud with five Olympic medals.
After that, the swimmer fell deep and is now in great trouble again.
According to reports in the New York Times and USA Today, the 38-year-old was involved in the storming of the Capitol last Wednesday.
The Olympic winner from Athens 2004 and Beijing 2008 is said to have been identified by several swimming colleagues.
Video recordings of the riots at the headquarters of the US Congress are said to show Keller that he wore a jacket from the American Olympic team in the Capitol that day.
So far, Keller is not suspected of having been violent.
He is not on lists that the police use to search for those involved in the storm.
The magazine "Swimming World" reports that Keller is a loyal supporter of Trump and has repeatedly publicly declared himself to be the elected US President.
However, his social media channels have been deleted or can no longer be accessed.

The former swimming star has so far been silent on the allegations.
Keller won silver at the 2000 Olympic Games in Sydney with the US relay in the 4 x 200-meter freestyle.
There are also two bronze medals in the 400 m freestyle in 2000 and 2004. He reached his sporting highlights with the US relay in 2004 and 2008, when he won gold in the 4 × 200 meter freestyle alongside superstars Michael Phelps and Ryan Lochte .
Keller loses his job
After the career, Keller fell into a deep hole.
In 2014 he divorced his wife.
In an interview he said he was homeless for ten months and not allowed to see his children for four years.
Apparently, Keller got back on his feet and most recently earned his living as a real estate agent for the Colorado and Ohio-based real estate agency Hoff & Leigh.
But he is now rid of this job.
The company announced on Tuesday that the ex-athlete was no longer employed by the company.
He had resigned as an independent contractor.
"Hoff & Leigh supports the right to freedom of expression and legitimate protest," the company announced in a statement: "But we cannot tolerate acts that break the law."
