Former Special Counsel Robert Mueller's investigation of Russian interference in the 2016 presidential campaign and possible coordination with former President Donald Trump's campaign lasted 674 days. The investigation of Mueller's investigation by U.S. Attorney John Durham, now himself a special counsel, hit Day 675 on Thursday, Marcy Wheeler points out at Emptywheel. "That means Durham's investigation has lasted one day longer than the entire Mueller investigation, which Republicans complained lasted far too long."

Mueller's limited investigation obtained nine convictions or guilty pleas and handed off many of its other cases to other federal prosecutors. (Trump pardoned many of his allies successfully prosecuted by Mueller.) Durham has notched one guilty plea, Kevin Clinesmith, and that was "based on conduct discovered by DOJ Inspector General Michael Horowitz," Wheeler notes. Little else is known about what Durham has been up to.
