Ibtihaj Muhammad, a U.S. Olympic fencer and the first Muslim woman to earn an Olympic medal for the U.S., said she was detained by customs officials without explanation.
Speaking Tuesday at the MAKERS conference, Muhammad said she was detained "a few weeks ago." It's not clear if it had to do with President Trump's controversial travel ban.
Muhammad won a bronze medal in team sabre at the 2016 Rio Olympics.
I can't tell you why it happened to me, but I know that I'm Muslim. I have an Arabic name.
Muhammad was also the first American woman to compete wearing a hijab.
My human response is to cry because I was so sad and upset and disheartened and just disappointed.
Ibtihaj said it was a "really hard two hours" but she was ultimately released.
Trump critics were quick to blame the travel ban for the incident.
Fellow Olympian Hope Solo said her story should 'offend every American.'
