Jul 24, 2019 Rep. Jim Jordan, R-Ohio, questioned former special counsel Robert Mueller during his July 24 testimony before the House Judiciary Committee about how the investigation began. Mueller said in his opening statement that he could not address those questions. Mueller, who led an investigation into Russian interference in the 2016 election and possible ties to President Donald Trump’s campaign, agreed to appear before Congress, but warned he would not go beyond what was already documented in his final report.
