WASHINGTON—President Barack Obama says America "couldn't be prouder of" its athletes who are competing in the Olympic Winter Games in Sochi, Russia.

The White House released a brief video of Obama Friday. The president tells the skiers, figure skaters, snowboarders, bobsledders and other members of Team USA that they are an inspiration to the nation.

Obama tells team members America will be watching and rooting for them.

First lady Michelle Obama expressed her pride in the team on Twitter.

The U.S. has sent some 230 athletes to the Sochi Olympics, the largest delegation ever for any country at the Winter Games.
