In his first comments on the Tokyo Olympics since taking office, U.S. President Joe Biden said Sunday that the decision on whether the games should go ahead this summer must be "based on science."

Speaking on the Westwood One radio show during a halftime interview at Super Bowl LV, Biden told host Jim Gray that Prime Minister Yoshihide Suga was "working very hard to be in a position to be able to safely open the games and have the games, and I think that has to be based on science.

"Whether or not it is safe for that to occur. My prayer is that it will be," he added.
