Joe Arpaio, who in 2017 became the first person to be pardoned by President Trump, announced Sunday an attempt to get his old job back as sheriff of Maricopa County, Arizona, in 2020.
The big picture: Arpaio is known for his hardline stances on immigration. He lost his bid for a 7th term as sheriff in 2016. In 2017, he was convicted of criminal contempt by a federal judge. In 2018, he lost an Arizona Republican Senate primary bid to then-Rep. Martha McSally.
