This is a message Trump blasted out on 22nd July 2021:

Republican Arizona State Senator Paul Boyer, a RINO if there ever was one, is doing everything in his power to hold up the damning Forensic Audit of Maricopa County which has been taking place over the last 90 days. The people of Arizona are demanding it. Boyer has been nothing but trouble, and nobody knows why. All we demand is Voter Integrity! He is being primaried by a strong and highly respected challenger, former Arizona State Representative Anthony Kern.
