(CNN) Former Arizona sheriff Joe Arpaio on Sunday announced he would seek another term as sheriff of Maricopa County, two years after President Donald Trump pardoned him. He had been convicted on charges of criminal contempt related to the hard-line tactics he used to crack down on undocumented immigrants.

"After consultation and approval from my wife of 61 years, Ava, I have decided to run to be reelected Sheriff," Arpaio said in a news release Sunday. "Watch out world! We are back!"

Arpaio -- who calls himself "America's toughest Sheriff" -- pledges his reelection will bring back some of his most controversial policing tools, including Tent City -- the infamous outdoor jail where inmates wore pink underwear and shuffled around in chain gangs. The facility became a symbol of Arpaio's 24-year tenure as sheriff. Critics have said the facility was demeaning for inmates, who stayed in scorching heat and ate calorie-controlled meals.

"I will continue to stand and fight to do the right thing for Arizona and America, and will never surrender," he said. "Those who break the law will have to deal with this Sheriff."

Arpaio, a vocal proponent of Trump's presidency, echoed the President's message Sunday, stating his goal as sheriff would be to "Make Maricopa County Safe Again." Trump pardoned Arpaio in 2017 before he was sentenced for being in contempt of court for continuing to make immigration arrests after a court ordered him to stop.
