Agents of the secret service should arrest him and take him into the White House where President Trump should dress him down in the Oval Office and make it public. Then, when he receives a proper apology. Let him go and find his own way back to where ever he lives. Then the IRS should audit him —No, that would happen only if Trump was a Democrat.
