WASHINGTON (AP) — Former White House chief of staff Reince Priebus was interviewed Friday by special counsel Robert Mueller's team of investigators as part of an ongoing investigation into potential coordination between Russia and the Trump campaign, his attorney said. "He was happy to answer all of their questions," the lawyer, William Burck, said in a statement. It was not immediately clear what questions Priebus was asked or how long the interview lasted. Priebus is one of several current and former White House aides expected to be interviewed by Mueller's team in the coming weeks.
