Vice President Mike Pence is scheduled to be in Yuma on Friday to stump for two-term Republican congresswoman Martha McSally.
She's vying for Arizona's open U.S. Senate seat against Democratic three-term congresswoman Kyrsten Sinema.
Last Friday, President Donald Trump was in Mesa to rally the GOP voter base and announce his support of McSally as the Nov. 6 general election draws near.
The McSally-Sinema race is considered one of the most competitive in the country.
Trump and Pence have been travelling around the nation to bolster Republican candidates.
