Michael Cohen got to watch Robert Mueller from the big house _ and he didn't like what he saw.
The former fixer and lawyer for President Donald Trump said in a jailhouse message that the special counsel blew a huge chance to hold the president accountable for his misdeeds.
"Mr. Mueller today had the world stage to answer questions regarding obstruction of justice and witness tampering. Sadly, his reluctance just continues to leave the debate open and those responsible free from prosecution ... for the moment," he said in a message reported by CNN.
"The American people deserve more!" he added.
Cohen, who was sentenced to three years in prison for his role in Trump's hush-money scheme to keep Stormy Daniels quiet, didn't explain how he got to watch the much-anticipated hearing at the Otisville, N.Y., federal prison.
Like many Americans, he apparently hoped Mueller would put some meat on the bones of his 400-plus-page report detailing Trump's efforts to undermine the probe into Russian interference in the 2016 election.
Mueller's halting testimony also failed to explain key questions like how Donald Trump Jr. got off scot-free despite apparently soliciting dirt on Hillary Clinton from Russian operatives.
Cohen urged lawmakers to reach out if they want a more complete version of Trump's activities than Mueller was willing to offer.
"If our elected officials want more information or clarification they know where to find me," Cohen wrote.
