Meghan McCain said Thursday that the Trump administration staffer who mocked her father’s brain cancer diagnosis has yet to apologize after promising she would.

"I was promised an apology, Kelly Sadler, publicly to my family. I did not receive that," McCain said. "This is not an administration that's capable of apologizing."

A source had told The Hill that Sadler had called McCain to say she was sorry, but the “View” co-host later said that the communications aide had in fact offered to apologize publicly, which has yet to happen.

"When I had a conversation with Kelly, I asked her to publicly apologize and she said she would," McCain, who has suggested that Sadler be fired, said on May 13. "I have not spoken to her since and I assume that it will never come."

"It's really good politics that they're doing right now," McCain said. "Because they are trying to change the narrative ... not talking about all the other bad things that are going on."

John McCain, who revealed last year that he has an aggressive form of brain cancer, has been undergoing treatment in Arizona.

Sadler's insult was in reference to his opposition to now-CIA Director Gina Haspel's nomination. Haspel was confirmed by the Senate on May 17 in a 54-45 vote.

Sadlery's joke was met with opposition from both Republican and Democratic lawmakers alike, with many demanding an official apology from the White House.

The administration has not apologized, but said earlier this month that the issue was being handled internally.

In the wake of the insult, Trump officials have focused on cracking down on leaks from the White House, instead of discussing the nature of Sadler's remark.
