"All previously announced campaign events involving the President's participation are in the process of being moved to virtual events or are being temporarily postponed," read a statement from the campaign.
The president, Vice President Mike Pence, Second Lady Karen Pence, and Ivanka Trump visited Phoenix in September weeks prior in an effort to gain more support from Arizonans as the state has become a critical battleground for the 2020 election.
This would have been Trump's sixth visit to Arizona this year.
Polls show Trump with a one-point edge over Biden in Arizona, according to an ABC News/Washington Post public opinion survey on Sept. 23.
Vice President Joe Biden, the Democratic nominee, is visiting Arizona on Oct. 8, although the details about the event have not been released yet. His outreach to Arizona has been driven by online events with surrogates, including earlier in September with his wife, Jill Biden, and running mate, California Sen. Kamala Harris.
