Secret Service spokesman Anthony Guglielmi claimed Monday that “we don’t independently maintain our own visitor logs because it’s a private residence.”

But Guglielmi’s tune had changed Thursday, when he said that “the Secret Service does generate law enforcement and criminal justice information records for various individuals who may come into contact with Secret Service protected sites.”

Meanwhile, Fox News quoted an unnamed source as promising that “the Secret Service is prepared to provide available background information on vetted guests to Biden’s residence if requested by Congress.”
