The FBI is investigating a claim by Navy veteran Richard Osthoff that Rep. George Santos misused funds from an online fundraising campaign intended to cover lifesaving surgery for Osthoff's service dog. Osthoff has provided the FBI with text messages and other records related to the campaign, and the US Attorney's Office in the Eastern District of New York is leading the investigation. Santos has not responded to questions about the matter, and the FBI has yet to comment.
