[Allen:] The U.S. first family and the British royals are publicly feuding. But it's all for a good cause. Barack Obama and Michelle Obama tweeted a challenge to Prince Harry over the upcoming Invictus Games, a competition for injured veterans. The prince responded and recruited Her Majesty for some help. Here is Phil Black with the story.
[Phil Black, Cnn Correspondent:] This is a celebrity Twitter war like no other, the Obamas versus the royals, the White House versus Kensington Palace. Michelle and Barack Obama attacked first, posting on a video on Twitter Friday. And Prince Harry returned fire with a video of his own, featuring what has to be his most powerful weapon: his grandmother.
[Henry, Prince Of Wales:] A message? Oh, from Michelle. How very amusing. Let us watch it together?
[Elizabeth Ii, Queen Of England:] Yes. So look.
[Michelle Obama, U.s. First Lady:] Remember when you told us to bring it at the Invictus Games?
[Barack Obama, President Of The United States:] Careful what you wish for.
[Unidentified Male:] Boom.
[Queen Elizabeth:] Really, please.
[Prince Harry:] Boom.
[Black:] "Boom, really, please," wouldn't normally be considered a winning verbal smackdown. But it carries a little more power when it comes from the queen. The Obamas and the royals spent quite a bit of time together in London recently and have clearly developed a rapport. This is a good-natured attempt to develop a bit of friendly rivalry ahead of the upcoming Invictus Games, a sporting event for injured military veterans. It's a cause that Prince Harry is heavily involved in Phil Black, CNN, London.
[Allen:] Great story there to end on, thanks for watching, I'm Natalie Allen. "WINNING POST" is coming up in a few moments, right after our headlines.
