No problem. The most disturbing part is that Trump made it clear, at the beginning of his presidency, that like previous presidents he has authority to declassify any material he wishes. They never bothered to challenge, all of these years, but today are concerned the American people might elect him again:
Trump stands by 'absolute right' to share sensitive information with Russia
For example, Joe could have shared classified information with our allies in Afghanistan, declassified it, although in Joe's case he never even mentioned the U.S. was pulling out and countries who came to our aid had stranded troops.
And it's not just challenge, they physically raided his residence, as they did with other backers of Trump, with armed personnel.
Here is the section of the Executive Order that exempts him:
(b) Information originated by the incumbent President or the incumbent Vice President; the incumbent President's White House Staff or the incumbent Vice President's Staff; committees, commissions, or boards appointed by the incumbent President; or other entities within the Executive Office of the President that solely advise and assist the incumbent President is exempted from the provisions of paragraph (a) of this section.
