The office of Arizona GOP Senate candidate Kari Lake was put on lockdown Tuesday after a campaign staffer opened a package with a "suspicious" substance. 

A campaign spokesperson told Fox News Digital that an intern at the campaign's Phoenix office opened an envelope with a suspicious substance and a note that said, "caution anthrax."

"The radical left, with help from the mainstream media, has escalated its attacks against me from baseless smears and legal harassment to physical threats. Today, my office received a suspicious envelope, potentially containing anthrax — an attempt to intimidate and silence me," Lake said in a statement. "This isn't just about me; it’s an attack on our movement. I won’t be intimidated, and those responsible must be brought to justice. The time to unite against these dangerous, un-American tactics is now."

Lake's Democratic opponent, Ruben Gallego wrote on X: "I condemn any act of violence of threats against Kari Lake, her office, or other public officials." 

"My thoughts are with the staffer involved, and I'm grateful for the swift response by @PhoenixPolice, @PHXFire, and the hazmat team," he said. "I hope everything is resolved safely and quickly."
