Arizona's Republican Gov. Doug Ducey has no plans to attend President Trump's rally in downtown Phoenix on Tuesday afternoon.

A spokesman for Ducey told the Arizona Republic he was looking forward to greeting Trump upon his arrival in the state but will not be following him to the campaign-style event.

"Gov. Ducey's focus has been working with law enforcement toward a safe event in downtown Phoenix for all those involved and in the area. That will continue to be his priority during the event and afterwards," spokesman Daniel Scarpinato said in a statement to the publication.

Ducey's decision to sit out the rally comes amid the president's strained relationship with the state's two Republican senators.

The president ripped Flake last week on Twitter, calling him "toxic" and promoting his primary opponent, Kelli Ward.

Flake was quickly defended by his in-state GOP colleague, Sen.

McCain also spoke out against Trump's response to the violence during a white supremacist rally in Charlottesville, Va., and famously helped kill the Senate's ObamaCare repeal-and-replace bill last month, drawing Trump's fury.

The rally also comes after the president said he is “seriously considering” pardoning the controversial former sheriff of Maricopa Country, Joe Arpaio.

Arpaio was found guilty of criminal contempt in July after he was ordered to stop racially profiling Latinos in his duties as sheriff.
