President Trump and the White House waited with the rest of the world on Sunday for the final report by special counsel Robert Mueller about his investigation into the Russian interference in the 2016 presidential election.

Deputy White House press secretary Hogan Gidley told reporters that neither he nor anyone else on staff had received the report or been briefed on it. Mueller notified the leaders of the Justice Department on Friday that it was complete.
