Jude Joffe-Block wrote for The Guardian about how Joe Arpaio's relationship with President Trump led to his pardon:
In early August, the 85-year-old Arizona lawman once known around the world as “America’s toughest sheriff” sat in his lonely private office, trying to puzzle out how to get his dire predicament noticed by his friend, President Donald Trump.
Former Maricopa County sheriff Joe Arpaio, who policed Arizona’s most populous county from 1993 to 2016 with theatrical stunts that included rounding up hapless Mexican immigrants, housing inmates in tent jails and forcing them to wear pink boxer shorts, was in trouble.
A few weeks before, Arpaio had been convicted of a federal crime – criminal contempt of court for defying a judicial order to stop his infamous immigration patrols. Arpaio faced up to six months in prison at his October sentencing.
The only thing that could save him was a presidential pardon.that could save him was a presidential pardon.
