President Barack Obama tweeted his congratulations to Diana Nyad, who on Saturday became the first person to swim from Cuba to Florida without a shark cage.
Nyad, 64, completed the 110-mile swim in about 53 hours. This was her fifth attempt at the swim -- she also tried three times in 2011 and 2012 and once in 1978.
Obama sent this tweet shortly after Nyad arrived in Florida:
Congratulations to @DianaNyad. Never give up on your dreams.
