The unsealing of a redacted search warrant, obtained by Special Counsel Jack Smith in January, to ransack President Trump’s account on X — formerly known as Twitter —  surfaces just how deep the prosecutor has dug in his effort to convict the 45th president for allegedly attempting to overturn the 2020 election.

The thought of government attorneys rifling through Mr. Trump’s account cannot be pleasing to the 45th president, whose use of the platform was crucial to his victory in the 2016 election and to defining his public persona during his presidency. Mr. Trump was “permanently suspended” from what was then Twitter in the days after January 6, 2021, when Twitter’s management claimed there was “the risk of further incitement of violence.”
