Former Colorado Gov. John Hickenlooper refused to comply with a subpoena to testify before the state’s Independent Ethics Commission on Thursday.

Hickenlooper, who briefly ran for the Democratic Party’s 2020 presidential nomination, was subpoenaed last week to testify about ethics complaints stemming from his time as governor but did not appear for questioning during a virtual hearing on Thursday. Instead, he sent his attorney, who argued that he should not have to show up because he was appealing a legal decision from Wednesday that said he must testify.
