Judge Andrew Napolitano said Wednesday that President Trump should take Michael Cohen's prison sentencing "with great gravity."

Cohen received a three-year sentence Wednesday after pleading guilty to tax evasion, campaign finance violations and lying to Congress about a Trump real estate project in Russia.

"The felony is [Trump] paying Michael Cohen to commit a felony," Napolitano said, referring to hush-money payments made to two women during the 2016 campaign.

Cohen made payments to adult film star Stormy Daniels and Playboy model Karen McDougal at the direction of Trump, prosecutors say.

Napolitano said that now, President Trump "is in the crosshairs" of federal prosecutors in the Southern District of New York and Robert Mueller's office in Washington, D.C.

Upon Cohen giving federal prosecutors evidence of such payments, he added, that evidence must be corroborated through other people or documents.

Napolitano also said that special prosecutor's memo on Cohen last week was "damning and novel information" that was packaged Wednesday in court.
