gigafact logo for fact briefs

The Arizona Center for Investigative Reporting is partnering with Gigafact to produce timely fact briefs, or quick-response fact checks, about trending claims relating to Arizona.

Gigafact is a nonprofit technology and information company working with newsrooms to correct misinformation. As part of our partnership, AZCIR will produce fact briefs to address statements about recent events or policies circulating online, deeming the claims accurate or inaccurate and providing documentation to back up our calls.

We’ll use this platform to push back on mis- and disinformation, publishing several fact briefs per week. This work isn’t about political opinions or clickbait, but rather providing fact-based, neutral analyses to help clarify topics that are important to our state and nation.

By adding these fact briefs to our existing investigative journalism, we can reach readers in new ways, often in a more timely and responsive manner.

Is Arizona home to thousands of volcanoes? 

Yes. Arizona has thousands of extinct volcanoes across seven volcanic fields. The San Francisco Volcanic Field in northern Arizona alone has produced more than 600 volcanoes, including Sunset Crater and the San Francisco Peaks.

Did Arizona experience record temperatures this past winter? 

Yes. The period from December 2025 through January 2026 marked Arizona’s warmest winter on record, according to data from the National Oceanic and Atmospheric Administration. The statewide average temperature for those two months was 48 degrees Fahrenheit, up from 44 degrees during the same period in 2024-2025.

Is Tempe requiring bars to make drink-spiking tests available?

Yes. The Tempe City Council unanimously approved an ordinance requiring certain restaurants and bars to sell drink-testing kits. Under the measure, businesses with Series 6 or Series 12 liquor licenses that serve alcohol more than three days per month between midnight and 2 a.m. must stock at least 10 kits at the start of each business day.

Could a new bill require law enforcement to work with ICE when making arrests?

Yes. Republican Sen. Wendy Rogers, R-Flagstaff, has introduced a bill that would compel state and local law enforcement to cooperate with federal immigration authorities, including Immigration and Customs Enforcement (ICE), during arrests. Senate Bill 1055 would require officers to notify ICE or Customs and Border Patrol when an arrestee is believed to be unlawfully present in the U.S.
