Bidens lawyers found the documents in a locked closet in an office in Penn Biden Center they were vacating and called the National Archives who were not even aware the docs were missing
In Trump case the National Archives knew that a bunch of documents were missing and made repeated requests and trips to Trumps home to retrieve them
Trump repeatedly claimed to have provided everything which was of course not true. Then he was subpoenaed for docs and still didn't provide the all (and his attorney lied in writing claiming all were provided) and only then did they have to get a search warrant and go retrieve the docs themselves
See any similarities here
Biden didn't have these docs in a desk at his home or in his sock drawer. Biden didn't repeatedly deny having the docs or stymie all requests (including a subpoena) to provide the docs. Bidens attorney's are the ones who informed the National Archives about the docs and the National Archives too possession of them the next day
BTW - the National Archives reported this to DOJ and Merrick Garland assigned U.S. Attorney for the Northern District of Illinois John Lausch (who was appointed by Trump) to find out how the material marked classified ended up at the Penn Biden Center.
Lausch was nominated to be U.S. attorney by former President Donald Trump, and he is one of only two current Trump-era U.S. attorneys still serving. The other is Delaware U.S. Attorney David Weiss, who is leading an investigation into the president's son, Hunter Biden.
What's the double standard again?
