Joe Arpaio, the former sheriff of Arizona's Maricopa County, said Tuesday he intends to run for US Senate in 2018. "Being a US senator is a little different than being the sheriff, because you can do a lot of things in the US Senate, and I have many plans, believe me," Arpaio said. President Donald Trump pardoned Arpaio last year after Arpaio violated the terms of a court order in a racial-profiling case. Arpaio has a lengthy, controversial track record that's sure to come up in his Senate campaign. The 85-year-old is best known for illegally detaining Latinos and keeping inmates in brutal jail conditions during his 24-year tenure as Sheriff in Maricopa County, Ariz.
