During an appearance on CNN’s “Erin Burnett Outfront,” Dershowitz said The Washington Post story would have severe implications if true and that other controversies surrounding the White House now pale in comparison.

“Let’s not minimize it,” he said. “Comey is in the wastebasket of history. Everything else is off the table. This is the most serious charge ever made against a sitting president of the United States. Let’s not underestimate it.”

Dershowitz also had a warning for Democrats, cautioning that it would be “a serious mistake” to conflate this with whether the Trump campaign had possible ties to Russian officials.

“We should not be talking about these other issues, we should be focusing only on this threat,” he said. “That’s where Republicans and Democrats can agree. Democrats should not be trying to take political advantage of this. This should be a national security issue pure and simple in isolation of everything else that went on before.”
