FLAGSTAFF, Ariz. (AP) — Vice President Mike Pence is planning rallies in Arizona on Friday, hoping to appeal to voters in counties that President Donald Trump lost in 2016.

The visits to the Flagstaff and Tucson airports come as both presidential candidates key in on battleground states ahead of Tuesday's election. Voters in Coconino and Pima counties supported Hillary Clinton in the last presidential election, but Arizona overall helped send Trump to the White House.

Pence is on a multi-state campaigning trip despite criticism from health experts who said he should be under quarantine after a coronavirus outbreak in his office. The White House approved the trip, saying Pence is exempt from quarantine under guidelines for essential workers. He tested negative for COVID-19.

Those attending the Arizona events will have their temperatures taken and be given a mask to wear.

Trump was in Arizona last week where he held rallies in Bullhead City and Goodyear. Vice presidential candidate Sen. Kamala Harris met with small groups of voters in Phoenix and Tucson on Wednesday.
