Egged on by Mr. Trump, Attorney General William P. Barr set out in 2019 to dig into their shared theory that the Russia investigation likely stemmed from a conspiracy by intelligence or law enforcement agencies. To lead the inquiry, Mr. Barr turned to a hard-nosed prosecutor named John H. Durham, and later granted him special counsel status to carry on after Mr. Trump left office.
But after almost four years — far longer than the Russia investigation itself — Mr. Durham’s work is coming to an end without uncovering anything like the deep state plot alleged by Mr. Trump and suspected by Mr. Barr.
Moreover, a monthslong review by The New York Times found that the main thrust of the Durham inquiry was marked by some of the very same flaws — including a strained justification for opening it and its role in fueling partisan conspiracy theories that would never be charged in court — that Trump allies claim characterized the Russia investigation.
