Barr has already made overtures to British intelligence officials, and last week the attorney general traveled to Italy, where he and Durham met senior Italian government officials and Barr asked the Italians to assist Durham, according to one person familiar with the matter, who spoke on the condition of anonymity to discuss a sensitive issue. It was not Barr's first trip to Italy to meet intelligence officials, the person said. The Trump administration has made similar requests of Australia, said people who discussed the interactions on the condition of anonymity because they involve an ongoing investigation and sensitive talks between governments.
