U.S. Attorney John Durham’s investigation into the origins of the Russia probe remains “full steam ahead,” a source familiar with his progress told Fox News, despite concerns from Republicans and allies of President Trump that the probe has been dormant following Election Day.

“Durham remains full steam ahead,” the source familiar with the investigation told Fox News.

Another source told Fox News that his investigation “is definitely still happening,” despite radio silence coming from the U.S. attorney from Connecticut.

RATCLIFFE SAYS THERE 'SHOULD BE' MORE INDICTMENTS IN DURHAM PROBE

Durham’s investigation has produced one criminal charge so far, against former FBI lawyer Kevin Clinesmith, who was accused of altering an email related to the surveillance of a former Trump campaign aide. That prosecution, though, did not allege a broader conspiracy within the FBI, and the conduct it involved had largely been laid out in a Justice Department inspector general report from last December.

After the Clinesmith charge, Durham’s team went silent. Two sources familiar with the investigation told Fox News over the summer that Durham was not finished with several lines of investigation, which he believed were “critical.”

One source told Fox News Durham had been “feeling more pressure to get this done and wrapped up” over the summer, but said that Durham “does not want this to be viewed political,” and would likely “punt it to after the election,” which he ultimately did.

Durham was appointed by Attorney General Bill Barr last year to investigate the origins of the FBI’s Russia probe, shortly after Special Counsel Robert Mueller completed his yearlong investigation into whether the Trump campaign colluded with the Russians to influence the 2016 presidential election.

Mueller’s investigation yielded no evidence of criminal conspiracy or coordination between the Trump campaign and Russian officials during the 2016 election.

Last month, Director of National Intelligence John Ratcliffe said he believed there “will be” and “should be” more indictments coming from Durham’s probe, based on “intelligence” he has access to.

“I think there will be more indictments,” Ratcliffe said in October. “Based on the intelligence I have access to, I certainly believe there should be.”

Ratcliffe also said that he has already provided 1,000 pages of material to the Justice Department to support Durham’s investigation.

“At my direction, the Office of the Director of National Intelligence has now provided almost 1,000 pages of materials to the Department of Justice in response to Mr. Durham’s document requests,” Ratcliffe said in a statement Wednesday. “I will continue to ensure the Intelligence Community’s responsiveness to the DOJ’s requests.”

Ratcliffe added that officials at ODNI “look forward to supporting the DOJ in further declassifications consistent with their investigation.”

“As the president has made clear, we must be appropriately transparent with the American people and give them the confidence that the extraordinary work of Intelligence professionals is never misused or politicized,” Ratcliffe said.
