Arizona was long a Republican stronghold but Democrats have made inroads and it is now a top battleground.

Monday marked the president's fifth stop to the Grand Canyon State this year as he trails Democratic challenger Joe Biden by several points ahead of the November election. Meanwhile, Biden has yet to pay Arizona a single visit.

The president previously visited Phoenix in May for a "Students for Trump" rally and held a campaign rally in Phoenix in February.

Vice President Mike Pence will also visit Phoenix on Friday to participate in a Libre Initiative Roundtable for Hispanic Heritage Month and a Veterans for Trump event.
