Appearing before Congress on Wednesday, former special counsel Robert Mueller will for the first time publicly detail what his investigation found regarding ties between Donald Trump's presidential election campaign and Russia, as well as potential efforts by the president to obstruct justice in the investigation. The highly anticipated appearance is expected to reinvigorate heated debate among Democrats over whether President Trump should be impeached. 

Mueller will appear before the House Judiciary Committee and the House Intelligence Committee. He made a brief statement at the Department of Justice in May, reiterating his team's consensus that Trump could not be exonerated, but also could not be charged with committing a crime.
