But Durham is still at work, looking at early aspects of the FBI investigation into the campaign. His relatively opaque investigation has now lasted longer than former special counsel Robert Mueller's investigation into Russian interference in the 2016 election and prosecution of dozens of Russians and Trump advisers.
Investigators with Durham's office -- having been delayed by pandemic restrictions last year -- are now arranging witness interviews, according to people familiar with the probe. Grand jury subpoenas also were being used to gather documents in recent months, the sources said.
Durham's probe is focused at least partly on actions by the FBI in its handling of a private intelligence dossier and the bureau's disclosures to the federal intelligence surveillance court, according to people briefed on the matter.
His investigation started in spring 2019 with then-Attorney General William Barr's publicly vague direction to scour intelligence gathering. Now, as Durham putters along, his work is still being watched by the vocally angry ex-President and his supporters. He is now positioned to deliver, at least, a report to Attorney General Merrick Garland that could ultimately be released publicly.
Barr extended Durham's tenure into the Biden administration by appointing him special counsel in October, just before the presidential election, as Trump and Republicans continued to believe a report was imminent. Over the course of last year, Durham had turned his focus toward looking at the leadership of then-CIA Director John Brennan and then-Director of National Intelligence James Clapper, before apparently moving on and continuing to prod the FBI.
