The move to turn into a criminal investigation has always been expected and it allows Durham to use subpoenas and comes as President Donald Trump faces pressure from negative headlines stemming from the impeachment investigation into the impeachment his relations with Ukraine. It is unclear what, if any, part of the Trump-Russia investigation is the target of Durham's criminal trial.
The investigation is led by Bar's suspicion that some of the officials who control the Trump campaign's counter-intelligence study in 201
Bar's embrace of these theories is equated with Trump's main complaint that he was the victim of a deep-state espionage operation that clouded his presidency.
The President has publicly called for investigations by former FBI Director James Komi, former CIA Director John Brennan and former Director of National Intelligence James Clapper, among others.
In recent weeks, the desire of the President of the Department of Justice to focus on his perceived critics has caused unpleasant problems for Durham and the Office.
Department officials said Bar was unaware that Trump had mentioned his name in a July conversation with the President of Ukraine, suggesting he was working with the attorney general and Rudy Giuliani, the president's personal lawyer whose business is close to the impeachment congressional investigation center. And a senior Justice official declined comment from acting White House chief of staff Mick Mulvey, who linked the freezing of aid from Ukraine to the Justice Department's probe.
The probe was unusual for a variety of reasons, not least because Bar took his hands – a role for tight control.
He, along with Durham, traveled to countries abroad, including Italy twice, to meet with officials seeking information.
One particular amendment for the Bar is Joseph Mifsud, a shady professor whose conversations with an associate of the Trump campaign became part of Robert Mueller's special investigation, according to a person familiar with the matter.
Mifsud is a regular fixture in conservative media stories that claim to work for US or Western intelligence and has been tasked with spying on the Trump campaign.
Bar also said that the review would include an examination of former work by British intelligence officer Christopher Steele, who compiled studies of Trump and Russia in a file commissioned by Fusion GPS, a research and investigation firm.
