So apparently this happened:

More from CNN:

In the aftermath of the comment — in which Sadler told a meeting that McCain’s opposition to CIA director nominee Gina Haspel didn’t matter because he’s “dying” — the White House refused to condemn her remark. She remained on the staff for nearly a month before departing.

Wow.

So, was Kelly Sadler’s comment about McCain the reason for her departure, or was it something else? According to CNN, the White House hasn’t yet responded to a request for comment. So it looks like we’ll have to wait and see.
