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.

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

Sen. Jeff Flake (Ariz.) condemned Trump in his new book, “Conscience of a Conservative,” which encourages other Republicans to stand up to the president for the good of the country.
