Former President Donald Trump said in a social media post that he's been informed by special counsel Jack Smith that he is a target of the criminal investigation into efforts to overturn the 2020 election.

"Deranged Jack Smith, the prosecutor with Joe Biden's DOJ, sent a letter (again, it was Sunday night!) stating that I am a TARGET of the January 6th Grand Jury investigation, and giving me a very short 4 days to report to the Grand Jury, which almost always means an Arrest and Indictment," Trump posted on Truth Social.

Trump also received a target letter earlier this year from Smith before he was indicted in the investigation into the mishandling of classified documents.

A spokesman for the special counsel declined to comment.
