Hickenlooper was scheduled to testify virtually before the state’s Independent Ethics Commission about his alleged violations of Colorado’s gift ban. He refused to appear because he believes the hearing would violate his due process rights.

“I believe our subpoena was very clear,” said Commissioner William Leone. Hickenlooper, he added, was “required to attend by virtue of that subpoena. He currently, in my view, is in contempt of that subpoena.”

The commission voted 5-0 to have the Attorney General’s Office enforce the subpoena. After the vote, commission Chair Elizabeth Espinosa Krupa said, “The Attorney General’s Office says it has a team on its way to enforce the subpoena.”
