John Durham, the U.S. attorney reviewing the origins of the 2016 counterintelligence investigation into Russia and the Trump campaign, is probing a wider timeline than previously known, according to multiple senior administration officials.

Fox News previously reported that Durham would be reviewing the days leading up to the 2016 election and through the inauguration.

However, based on what he has been finding, Durham has expanded his investigation adding agents and resources, the senior administration officials said. The timeline has grown from the beginning of the probe through the election and now has included a post-election timeline through the spring of 2017, up to when Robert Mueller was named special counsel.

Attorney General Bill Barr and Durham traveled to Italy recently to talk to law enforcement officials there about the probe and have also had conversations with officials in the U.K. and Australia about the investigation, according to multiple sources familiar with the meetings.
