The Associated Press’ twitter account on Tuesday was compromised by hackers who sent out the following “breaking news” alert:

Associated Press Twitter Feed Hacked, Obama Report Injured in White House Explosions

Screen shot.

“Breaking: Two Explosions in the White House and Barack Obama is injured,” the false “report” reads.

Thankfully, this isn’t true. There were no explosions at the White House and the president is doing just fine:

MORE: "The President is fine," says Press Sec. Jay Carney, as AP reporter says news service Twitter feed was hacked.

The AP moved quickly to suspend its account and soon sent out the following messages to calm an understandable shocked nation:

All, AP's Twitter accounts will be suspended until we can be assured of their security. Do not respond to any news posted by these accounts.

Now aside from being a terrible “joke,” the false tweet revealed something remarkable:

Associated Press Twitter Feed Hacked, Obama Report Injured in White House Explosions

See that?

In the time it took for the AP to lock down its account, U.S. markets took a hard, hard, hard downward turn. The implication is terrifying: Twitter apparently has the power to sink the markets. This could get real interesting, real fast.
