Hackers Breach White House's Unclassified Computer Network

Hackers recently breached the White House's unclassified computer network, resulting in temporary outages as cybersecurity experts work to contain the situation, a senior administration official confirmed.

Some elements of the unclassified Executive Office of the President network have been affected, according to a statement from the administration official.

"Our actions are ongoing, and some have resulted in some temporary outages and loss of connectivity for our users," the official said in the statement. "Our computers and systems have not been damaged, though some elements of the unclassified network have been affected. The temporary outages and loss of connectivity for our users is solely the result of measures we have taken to defend our networks."

The FBI, Secret Service and National Security Agency are investigating the intrusion.
