Colorado authorities are investigating possible threats against state Supreme Court justices, Denver police have said, one week after the court¡¯s decision barring former U.S. President Donald Trump from the state¡¯s presidential primary ballot.

The Denver Police Department also said Tuesday that it was providing ¡°extra patrols¡± around the homes of the justices, who ruled 4-3 on Dec. 19 that Trump should be disqualified under a little-known clause of the U.S. Constitution¡¯s 14th Amendment for engaging in insurrection.

Two nights later, Denver police officers were dispatched to the home of one of the justices in response to a call for service that police afterward described as an apparent ¡°hoax report,¡± adding that they were still investigating the incident.
