The Social Security numbers and other private information of more than 400 former congressional staffers and others were made public Tuesday in the unredacted files related to the assassination of President John F. Kennedy, according to a review by The Washington Post.

More than 60,000 pages related to the 1963 assassination were released this week by the Trump administration. Many of the pages had been previously disclosed, but with redactions. Many, but not all, redactions have been removed. The records have been posted to the National Archives webpage under the headline “JFK Assassination Records — 2025 Documents Release.”

After The Post reported the inadvertent disclosure Wednesday, The White House rushed to mitigate the impact. The National Archives started screening the documents for Social Security numbers so that the Social Security Administration could identify living individuals and issue them new numbers, a White House official said. In the meantime, the official, who spoke on the condition of anonymity because they were not authorized to publicly discuss the plan, said those affected will receive free credit monitoring.
