During an Oct. 15 Planning and Zoning Commission meeting, she spoke out in support of allowing the project to proceed, noting she was there on behalf of Active Infrastructure and that she is co-chair of the AI Infrastructure Coalition.

Active Infrastructure is the developer that had been pushing for the project.

"Chandler right now has the opportunity to determine how and when these new, innovative AI data enters will be built. When federal preemption comes, we'll no longer have that privilege," Sinema warned.
