The Federal Bureau of Investigations, FBI says it is assisting the police department in Denver with investigations into possible threats against state Supreme Court justices.
The probe comes a week after the court barred former US President Donald Trump from the state’s presidential primary ballot.
The justices ruled 4-3 on December 19 that Trump should be disqualified for engaging in insurrection.
After two days, Denver police were called to one of the justice’s homes in what was later described as a hoax report but the incident is still being investigated.
