Former Maricopa County Sheriff Joe Arpaio tweeted his thanks Friday night to President Trump for pardoning him of a criminal conviction and went on to ask the public to donate to his legal fund.

"Thank you @realdonaldtrump for seeing my conviction for what it is: a political witch hunt by holdovers in the Obama justice department! I am humbled and incredibly grateful for President Trump. I look fwd to putting this chapter behind me and helping to #MAGA," Arpaio tweeted late Friday.

"I also thank my loyal supporters, who stood shoulder to shoulder w/ me in this fight, and throughout my career. For those who are asking . . how they can con't [sic] to help, a donation to my Legal fund go directly to paying off legal fees from this fight," Arpaio added.

Arpaio told Fox News host Sean Hannity on Friday evening he plans to hold a news conference next week to discuss "abuse" he says he endured from the judicial system and politics in general

Trump pardoned Arpaio on Friday after a judge ruled that he was in criminal contempt of court.

"Today, President Donald J. Trump granted a Presidential pardon to Joe Arpaio, former Sheriff of Maricopa County, Arizona," the White House announced Friday evening. "Throughout his time as Sheriff, Arpaio continued his life's work of protecting the public from the scourges of crime and illegal immigration. Sheriff Joe Arpaio is now eighty-five years old, and after more than fifty years of admirable service to our Nation, he is worthy candidate for a Presidential pardon."

Last month, U.S. District Judge Susan Bolton found Arpaio in criminal contempt of court for not following a different judge's orders to stop traffic patrols that targeted illegal immigrants. Arpaio was found in civil contempt of court in May.

Arpaio said Wednesday that the judge was biased against him and said he will air his grievances at a future date.

"I don't want to get too much into legal -- during a civil case. The judge and I won't go into all of his bias, believe me, but it will come out again. No one will print it, but he pushed us over to another judge for contempt of court," Arpaio said.

"And they charged me with the wrong charge. No jury. I can go on and on. Once again, the truth will come out," added Arpaio.

The career law enforcement official complained that while he has only received two parking tickets in his life, he has been accused and convicted of these unrelated crimes.

Arpaio's defense argued during the second trial that he was unaware of the limitations the first judge had ordered, which he was later held in contempt of violating.

Arpaio's sentencing had been scheduled to begin Oct. 5.
