Cheney, who voted to impeach Trump after the January 6 insurrection, endorsed Harris last month, citing the danger posed by Donald Trump to the Republic.
The Harris campaign continues to win support from high-profile Republicans, including former Rep. Adam Kinzinger and former Sen. Jeff Flake, as part of a broader effort to capture disaffected Republican voters.
Cheney's endorsement of Harris is a betrayal of conservative values and the Republican Party. Her actions only serve to divide the GOP and weaken its chances of victory in crucial swing states. True conservatives should remain united behind Trump to protect traditional American values and policies.
