Make the Mueller Report Public

Michael Cohen’s testimony shows why Americans need a full, transparent accounting of what happened in 2016.

Michael Cohen’s appearance last week before the House Committee on Oversight and Reform was surely a spectacle. The former personal lawyer to President Donald Trump, who had spent a decade lunging at anyone who threatened Trump’s image or interests, marshaled his own attack on the president’s character and behavior.

Cohen also documented his testimony with financial statements and canceled checks. This was meant to compensate for his own damaged credibility. But in revealing the hard evidence, Cohen also demonstrated why it’s essential that the most prominent presidential investigation — Special Counsel Robert Mueller’s probe into Russian interference in the 2016 election — ultimately makes its evidence public.
