When ABC anchor George Stephanopoulos remarked that type of cyber crime was happening "right into the White House," Obama sidestepped.
"I'm not confirming that that's what happened," Obama said, before continuing to warn of websites that sell individuals' credit card information.
Spokespeople for the Secret Service and FBI said Tuesday they were investigating a website that appeared to have posted Social Security numbers, credit reports, home addresses and personal banking information for top government officials, including Michelle Obama, Vice President Biden and Attorney General Eric Holder.
Other celebrities' information was also posted, including that of former Alaska Gov. Sarah Palin and Los Angeles Police Department (LAPD) Chief Charles Beck. A spokeswoman for the LAPD confirmed that the information posted about the police chief was correct.
