The U.S. Justice Department is expecting a number of current and former government officials to request reimbursement for legal fees that were incurred during the Russia investigation, in which former Special Counsel Robert Mueller III's team interviewed dozens of federal employees about their conversations with President Donald Trump and senior White House staff.

The Justice Department's Office of Legal Counsel concluded in a new memo that the attorney general has the power to authorize the reimbursement to current and former government officials who met with Mueller's team "under threat of subpoena concerning information obtained during the course of performing their federal duties."
