Trump pardons Joe Arpaio

Trump has granted a presidential pardon to former Sheriff Joe Arpaio, of Maricopa County, Arizona. The memo mentions his "admirable" and "selfless public service." Why it matters: Choosing Arpaio as the first pardon will enrage half the country, but Trump won't care. The way Trump sees it, he genuinely believes an injustice was done to Arpaio and he sees this as helping somebody who was loyal to him throughout the campaign. Trump viewed Arpaio's support -- along with Jeff Sessions' -- as crucial to solidifying his credentials on being tough on the border.
