President Joe Biden may have used pseudonyms in nearly 5,400 emails, electronic records and documents when he was vice president, a bombshell letter from the National Archives and Records Administration reveals.

The trove of communications was confirmed after the Southeastern Legal Foundation (SLF) filed a Freedom of Information Act (FOIA) for emails connected to aliases allegedly used by Biden, including Robin Ware, Robert L. Peters, and JRB Ware.

Republicans have been demanding the release of the emails they say could show Biden used the names to discuss foreign business with his son and share information on countries where he was doing deals.

The White House has insisted Biden was never in business with his son, and vice presidents and high-level government officials often use pseudonyms to prevent being inundated with spam and emails from the public.

At the time, the Obama administration dismissed criticism the communications were 'secret' because they were all archived.

But the sheer volume of emails raises questions over whether then-VP Biden broke the 'absolute wall' he said he maintained between the 'the personal and private, and the government'. 

Emails from Hunter's laptop also reveal business partners referred to Biden as the 'big guy'.

The SLF submitted the FOIA request in June 2022 and the results appear to confirm that Biden was using the emails connected to the aliases.

Biden used various private email addresses from which he sometimes sent, received and forwarded government correspondence.
