3:02 PM PT -- He has since expanded his statement, now saying, "Seriously, folks? This is my final comment on this. I neither said nor implied any such thing. Despite headlines claiming otherwise, in my post, I absolutely did not call for an act of violence or threaten a U.S. president as many other celebrities have done in the past. I suggest you re-read my actual post and pay attention to the words before believing this nonsense."

He continues, "It’s my position, which I am entitled to have, that some of our nations leaders in Washington have lost their way, and corruption runs rampant, both on our nation’s borders and abroad. Transparency and accountability must happen in order for our constitutional republic to survive. There is no threat implied or otherwise in that statement."

1:58 PM PT -- John tells us he meant no harm in the tweet, saying, "Seriously, folks? I said no such thing. Despite headlines claiming otherwise, I absolutely did not call for an act of violence or threaten a U.S. president."

"The Dukes of Hazzard" star John Schneider will likely have a visit from the Secret Service in the near future ... because he made a social media death threat against President Biden.

The actor, famous for playing Bo Duke on the iconic TV show, posted on Twitter Wednesday, stating both Biden and his son, Hunter Biden, "should be publicly hung." John's full tweet read, "Mr. President, I believe you are guilty of treason and should be publicly hung. Your son too. Your response is..? Sincerely, John Schneider."

John's threat has since been deleted ... and was a direct reply to Biden's post about Donald Trump, where POTUS took shots at the indicted former president.

Judging by his tweet, John thinks Biden is guilty of treason too.

Funny enough, Wednesday, the same day he sent the threat, was a pretty eventful day for John ... because he was also revealed as the secret celebrity hiding behind the donut costume on FOX's singing competition show, "The Masked Singer."

John's account also has other replies where he mentions Biden and treason ... and there's another recent post ripping Dr. Anthony Fauci as "Treasonous."

So, there seems to be a theme here ... but now, it's escalated to death threats.

We reached out to John's camp ... so far no word back.
