Among those whose data was posted were Obama, Mueller, US Vice President Joe Biden, Attorney General Eric Holder, former secretary of state Hillary Clinton and celebrities including Britney Spears, Mel Gibson and Ashton Kutcher.

The White House declined to comment, and credit rating agencies involved—Transunion, Equifax, Experian—did not immediately comment.
