Trump tweets plug for book by notorious Sheriff David Clarke

Not content with abetting only one violent sheriff, President Trump on Sunday supported another: David Clarke, the notorious Wisconsin lawman with a long history of alleged abuse.

Trump started his morning by tweeting an endorsement for Clarke's book "Cop Under Fire," which has been out since February.The promotional tweet came more than an hour before Trump tweeted about Hurricane Harvey, which has ravaged Houston, Texas and killed at least six people.

In his tweet, Trump called Clarke "a great guy" and said the book is "highly recommended."

Clarke is an avowed Trump supporter who accepted, but then rescinded, a position as assistant secretary at the Department of Homeland Security.

Clarke is at the center of several lawsuits accusing him and his employees in Milwaukee County of neglecting and abusing inmates, sometimes allegedly leading to their deaths. One lawsuit alleges that a mother was forced to give birth in a jail cell alone, leading to the baby's death; another says an inmate died of dehydration after being denied water for a week.

Trump's free advertising for Clarke came two days after Trump pardoned Joe Arpaio, the former sheriff for Maricopa County in Arizona, who shares Clarke's reputation for harsh punishment.

Arpaio had been convicted for criminal contempt after violating a court order to stop policing tactics that discriminated against Latinos. The U.S. Justice Department in 2011 said Arpaio's office established the worst patterns of racial profiling the agency had investigated.

Arpaio detained inmates in a so-called "Tent City," where they forced into labor under Arizona's blazing temperatures. At least three inmates died there in restraint chairs. Arpaio approvingly compared his lockup to a concentration camp.

Arpaio, another Trump supporter, was set to serve up to six months in jail before Trump jumped in. The President's pardon has been widely criticized on the left and right, with many critics deeming it an abuse of power.
