White House (CNN)–As Michael Phelps swam into the history books on Tuesday, becoming the most decorated Olympian of all time, it didn't go unnoticed by the number one fan in the White House.
"Congrats to Michael Phelps for breaking the all-time Olympic medal record. You've made your country proud. -bo," President Obama tweeted to his 18 million followers.
Phelps, who won his 19th Olympic medal as the anchor of the gold winning USA 4×200 meter freestyle relay team, tweeted back, "Thank you Mr. President!! It's an honor representing the #USA !! The best country in the world!!"
An avid sports fan, it's no surprise the commander in chief was watching. "He is a sports fan, as everyone knows," Jay Carney said at last Friday's press briefing. "I heard him the other day. He's like, 'I love the Olympics. I can't wait for the Olympics to start." The president also appointed First Lady Michelle Obama to lead the American delegation to the London games.
