In her latest rebuke of Trump, Cheney openly questioned whether the president was aware of reports that the Russians offered Afghan militants bounties to kill U.S. troops and demanded that the administration take a more aggressive posture toward the Kremlin.

And a few days before, Cheney took a veiled shot at Trump by tweeting out a photo of her dad wearing a mask with the caption: “Dick Cheney says WEAR A MASK. #realmenwearmasks” — the same phrase that Speaker Nancy Pelosi has been using to take digs at Trump, and one that touches on a sensitive subject for the president: his manhood.

Cheney’s colleagues say she’s avoided Trump’s wrath because there’s no question about her credentials — the name Cheney is practically synonymous with conservatism — and because she’s strategic about her battles with Trump.

Plus, Cheney aggressively defends the president in the spots where it matters to the White House, like impeachment, and spends far more time attacking Trump’s favorite foes, such as Pelosi or China. That has enabled Cheney to carve out her own space in the party, without alienating Trump’s base or jeopardizing her bona fides on the right.
