The US Secret Service is investigating whether new Director Julia Pierson's personal information was hacked and published on a website.
The information on the website included a Social Security number, phone numbers, and a credit report that includes accounts with The Home Depot, Sears, and Macy's.
It was unclear how much of the data that appeared on www.exposed.re was accurate or who posted it. The website appeared to have information about other government officials and celebrities that had been published online previously at another Internet address, www.exposed.su.
"We are investigating and we are aware of the matter," a Secret Service spokesman said without commenting further.
Pierson was sworn into office on March 27 and is the first woman to head the agency which protects the president.
An FBI spokeswoman said "we're aware of the reports" but would not say whether the FBI was investigating.
