An envelope containing “suspicious white powder” was delivered to the campaign headquarters of the Republican candidate for governor of Arizona on Saturday.
A campaign spokesman told CNN that a staffer at the Kari Lake campaign headquarters in Phoenix opened an envelope containing white power.
Items discovered during the investigation will be tested at a lab in Arizona, a law enforcement source familiar with the investigation told CNN. No evidence was sent to the FBI lab in Quantico, the source said.
Earlier Sunday, Lake campaign spokesman Colton Duncan told CNN via text message that law enforcement had seized two envelopes and “sent them to experts at Quantico for review.”
Lake told reporters Sunday night that her campaign was initially told the suspicious mail was sent to Quantico for review, “but apparently there’s a lab closer and they actually sent the substance there, so we’ll find out what it was.” ”
Phoenix police told CNN in an email that they responded to a “property call” at 40th Street and Camelback Road.
“When the officers arrived, they learned that there were suspicious items in the post office. Additional resources responded to retrieve the items and secure the area,” Sgt. Phil Krynsky told CNN. “There are no reports of injuries and the investigation remains ongoing.”
CNN has contacted the FBI’s Phoenix office for more information.
Earlier Sunday, Lake’s team said it was taking the threat “extremely seriously” and thanked authorities for looking into the incident. Duncan said the staff member is under medical supervision.
“Until then, know that our resolve has never been higher and that we cannot be intimidated. We continue to move full speed ahead to win this election on Tuesday,” Duncan said.
Arizona has been a hotbed of extremist anger and threats against political and election officials. These threats were directed at both Democratic and Republican leaders.
“We are in dangerous times. This is not the first time we have been … threatened, I have been threatened many times,” Lake told reporters at a pre-campaign event in Queen Creek.
“We’re going to get to the bottom of this, I really don’t want to rush it, I want investigators to look into this and I really want to find the people who sent this because it’s wrong that this is happening.”
Lake’s Democratic opponent, current Arizona Secretary of State Katie Hobbs, condemned the behavior toward her opponent and her staff, saying the incident was “incredibly troubling.”
“Political violence, threats or intimidation have no place in our democracy,” Hobbs said in a statement. “I strongly condemn this threatening behavior towards Lake and her staff.”
Hobbs’ election office was broken into late last month. A suspect was arrested in that case, but police said the man had recently broken into at least one other office. Police have not linked the suspect to political motivation.
Arizona Democratic Sen. Mark Kelly called the incident “horrific” on Sunday.
“There is no place in our democracy for this kind of thing,” Kelly told CNN at a campaign event in Tucson. “But we don’t need anyone to do something like that. It’s just wrong. And hopefully there will be an investigation and they will find out who did this and arrest them and prosecute them.”
