Former Arizona Sheriff Joe Arpaio 'strongly considering' Senate run

The controversial former sheriff was pardoned by Trump in August.

The former sheriff of Maricopa County said he has not spoken with the president about his thoughts of running for the Senate, but added, "if I run, I'm running for him."

And the praise was reciprocal: As a candidate, Trump made immigration a central fixture of his campaign with his promise to build a southern border wall and frequently touted Arpaio's endorsement as evidence of his relative toughness of immigration issues.

"[Arpaio] is the best. So he endorsed Donald Trump and that means that my plan is the best, my plan is the strongest,” Trump said of Arpaio at a 2016 campaign rally in Oklahoma City.
