The Obamas Prove They're Ready for the Invictus Games

— -- With the Invictus Games just around the corner, President Obama and First Lady Michelle Obama showed Prince Harry they’re not messing around.

In a short video message on Twitter, the two called out Prince Harry, letting him know they’re ready for anything.

“Careful what you wish for,” President Obama warns.

In response, Prince Harry proved he can handle the playful trash talk with some help from Queen Elizabeth.

The Invictus Games, an international sporting event started by the prince for wounded, injured and sick service personnel, will be held in Orlando May 8-12.

ESPN, a sister company of ABC News, will begin its coverage of the Invictus Games on ESPN2 on May 8.
