Prosecutor to examine Russia probe origins.

Attorney General William Barr has appointed a U.S. attorney to examine the origins of the Russia investigation and determine if intelligence collection involving the Trump campaign was “lawful and appropriate,” a person familiar with the matter told The Associated Press on Monday.

Barr appointed John Durham, the U.S. attorney in Connecticut, to conduct the inquiry, the person said. The person could not discuss the matter publicly and spoke to the AP on condition of anonymity.

Durham’s appointment comes about a month after Barr told members of Congress he believed “spying did occur” on the Trump campaign in 2016.
