The Justice Department revealed that U.S. Attorney John Durham, picked by Attorney General William Barr to look into the origins of the Trump-Russia investigation, is investigating whether Ukraine was involved in any 2016 election efforts.

“A Department of Justice team led by U.S. Attorney John Durham is separately exploring the extent to which a number of countries, including Ukraine, played a role in the counterintelligence investigation directed at the Trump campaign during the 2016 election,” DOJ spokeswoman Kerri Kupec said Wednesday. “While the Attorney General has yet to contact Ukraine in connection with this investigation, certain Ukrainians who are not members of the government have volunteered information to Mr. Durham, which he is evaluating.”
