The U.S. Secret Service is prepared to offer names of individuals who visited President Biden's Wilmington, Delaware, home if requested by Congress, Fox News has learned.

The White House continues to insist that there exists no formal visitor log for the personal residence where two troves of classified documents were found.

While the White House has not kept a formal list, the Secret Service does collect information on guests with regular access to the home. 

Retention of the names of those vetted by the Secret Service depends on a variety of factors, including proximity to the president and the nature of the background check.

"The Secret Service does not maintain visitor logs at the private residences of protectees," said U.S. Secret Service chief of communications Anthony Guglielmi. "While 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, we are not able to comment further as this speaks to the means and methods of our protective operations."

A source familiar with the situation told Fox News that the Secret Service is prepared to provide available background information on vetted guests to Biden's residence if requested by Congress.

"Will you commit to speak to the special counsel?" one reporter could be heard asking in reference to Robert Hur, who has been appointed to investigate the documents and how they were kept.

Biden did not acknowledge the questions as he smiled while White House staff urgently rushed the media out of the room.
