New Mexico resident Ryan Martinez, 23, was taken into custody as the suspected shooter after leaving the event in a car, said Rio Arriba County sheriff's office Major Lorenzo Aguilar.
A Hopi Native American man from Seattle, Washington, was shot, according to Peixinho.
The county halted the reinstallation of 16th-century Spanish conquistador Juan de Onate's statue planned for Thursday after protests over the return of the bronze figure, removed three years ago during nationwide anti-racism demonstrations.
The Santa Fe New Mexican showed a picture of a man at the protest it identified as Martinez wearing a red MAGA hat.
Onate is known for the 1599 massacre of a pueblo tribe, leading a group of Spanish settlers into what is now New Mexico.
