Sensitive personal information, including Social Security numbers, was exposed in newly unredacted John F. Kennedy assassination documents released this week, sparking outrage among those affected.

Among them is Joseph diGenova, a former campaign lawyer for President Donald Trump, who said he intends to sue the U.S. National Archives and Records Administration for violating privacy laws. He also expressed deep concerns about identity theft.

“It should not have happened,” diGenova said in a phone interview with the Associated Press on Thursday. “I think it’s the result of incompetent people doing the reviewing. I don’t believe it had anything to do with rushing the process. The people who reviewed these documents did not do their job.”

His personal information was included in records related to his work with a U.S. Senate select committee that investigated government abuses of power in the 1970s, including domestic surveillance.

This is a developing news story and will be updated as more information is available.
