Vice President Pence praised former Maricopa County Sheriff Joe Arpaio, who was convicted of contempt of court, as a “tireless champion of … the rule of law” during an event in Arizona on Tuesday.

Pence said at the tax event that he was “honored” by the former sheriff’s attendance, and called Arpaio a “great friend of this president and tireless champion of strong borders and the rule of law,” to cheers from the crowd.

He argued in the filing that Judge Susan Bolton “refused to give the Sheriff a trial by jury,” and that her “verdict was completely unsupported by the evidence, among numerous other reasons.”

Bolton did not sentence Arpaio after Trump’s pardon, but also did not vacate her ruling against the former sheriff.

Arpaio is also well-known for helping to popularize the "birther" conspiracy that questioned former President Obama’s birthplace, a fringe theory that Trump also promoted.

He has long called his conviction politically motivated.
