Robert Mueller’s testimony on Wednesday before a congressional panel “could be productive” for Americans and help them understand the circumstances of Russia’s interference in the 2016 presidential election, Gov. Andrew Cuomo said Monday in a radio interview.

“People want to know what really happened,” Cuomo said in the interview on WAMC. “I know this is all polarized now and Democrats, Republicans they see it through a polarized lens, but I think he can actually bring some sobriety to the conversation.”

Mueller’s televised testimony, perhaps the most anticipated in a generation, presents stakes for both parties. Democrats will seek to draw out Mueller, who stayed within the parameters of his report detailing Russia’s efforts to sway the outcome of the election and President Donald Trump’s efforts to stymie the investigation.

Mueller concluded there was not sufficient evidence to find Trump’s campaign worked with Russia, but did not exonerate the president on the question of obstruction.

Cuomo said in the interview the testimony should be a chance for facts to be publicly aired.

“Let’s end some of this hyperbolic emotional rhetoric,” Cuomo said. “He’s a well-respected source. Let’s just understand some facts before we come to conclusions.”
