On Friday, her PAC, The Great Task, announced it was spending more than half a million dollars urging the Arizona voters to reject both GOP gubernatorial candidate Kari Lake and GOP candidate for secretary of state Mark Finchem.

Within hours, Lake posted a letter on Twitter thanking Cheney for her "in-kind contribution" to her campaign:

Liz Cheney, Defeated Member of Congress (WY):

Thank you for your generous in-kind contribution to my campaign. Your recent television ad urging Arizonans not to vote for me is doing just the opposite. Our campaign donations are skyrocketing and our website nearly crashed from traffic as people rushed to learn more about my plan to put Arizona First and join our historic political movement.

In fact, my team tells me your commercial should add another 10 points to our lead. I guess that's why they call the Cheney anti-endorsement the gift that keeps on giving….

Thank you again for the huge boost to our campaign! Enjoy your forced retirement from politics. I know America will rest easier knowing that one more warmonger is out of office.
