Simone Manuel's victory in the pool is a historic triumph

Simone Manuel swam her way to a historic victory in Rio on Thursday, holding off world record holder Cate Campbell of Australia to grab 100 meter freestyle gold in a tie with Canada's Penny Oleksiak. 
Manuel clocked in at a stunning 52.70 seconds. It was a new Olympic record.
It was even more significant than that, though: Manuel became the first female African-American swimmer to win gold in an individual event.
