Asked Sunday by CNN’s Jake Tapper on “State of the Union” whether voters should interpret his refusal to engage Clinton on the email issue to mean that Clinton did nothing wrong, Sanders replied with a firm, “No.”

“Nope, nope. That is not, I think, a fair assessment. That is, I think, a very serious issue,” Sanders said. “There is a legal process taking place, I do not want to politicize that issue. It is not my style.”

Sanders famously said in the first Democratic debate that he was tired of hearing about Clinton’s “damn emails,” brushing aside one of the biggest issues Republicans have raised to attack Clinton during the 2016 presidential cycle.
