The Secret Service is refusing to hand over emails that identify visitors to President Biden’s homes in Delaware, telling The NY Post in response to a Freedom of Information Act request that it can’t legally do so. The information could bear on high-profile controversies involving the Biden family’s business dealings and the president’s mishandled classified records.

A Secret Service FOIA officer cited a federal appeals court ruling in New York regarding visitor information for former President Donald Trump’s residences, even though the ruling doesn’t bind the actions of officials in Delaware or in DC. “Please be advised that emails reflecting visitors to President Biden’s residences in Wilmington, Delaware and Rehoboth Beach, Delaware are not agency records subject to the FOIA. See Doyle v. U.S. Dep’t of Homeland Sec., 959 F.3d 72 (2d Cir. 2020) (finding that emails regarding expected visitors to the sitting President’s residence were not agency records subject to the FOIA.),” the officer said in a letter.

The Secret Service claimed last year that “no records were located” showing logs of Biden’s Delaware visitors in response to a FOIA request filed by The Post.
