President Donald Trump’s pardon of the controversial former Arizona Sheriff Joe Arpaio has been challenged by two advocacy groups, one of which includes Obama administration lawyers, who allege that the commander-in-chief’s pardon of Arpaio was an unconstitutional overreach of executive authority.

As we all know, Sheriff Joe Arpaio was convicted by the Obama Justice Department of violating a 2001 injunction barring his officers from stopping and detaining Latino motorists solely on the suspicion of being illegal immigrants. Fortunately, Trump stepped in to save the day and pardon the sheriff for his “selfless public service.”

The first one seeking to file an amicus brief in an Arizona district court where Arpaio is seeking to vacate a conviction after Trump pardoned him was a public interest law firm, the Roderick and Solange MacArthur Justice Center. The brief however, was turned down by a judge on procedural grounds.

The second advocacy group consisted of several Obama administration lawyers called the Protect Democracy Project, filed another separate brief this Monday, in which they urged Bolton to first decide whether the pardon was constitutional before the case was dismissed.

And as if that was not enough, at last, the Coalition to Preserve Protect and Defend, argued that the president’s pardon will only remove the court’s ability to enforce its own orders, writing:

“The result would be an executive branch freed from the judicial scrutiny required to assure compliance with the dictates of the Bill of Rights and other constitutional safeguards.”

President Trump however, believed strongly in Sheriff Joe, calling him a patriot who loves our country, protected our borders and pardoned him, believing that the people of Arizona that know him and the Sheriff, agree with him.
