I doubt it's the worst thing she's had to swallow working for Trump.
As it is, there's two stories going around about the Conways. The first is from an article on Kellyanne, in which she made a statement that George's opposition to Trump puts considerable strain on their marriage - and tried to attribute it to "a source close to the couple" before the journalist reminded her that she'd already said that everything was on the record and should be attributed to her. The second is a conspiracy theory which states that the two of them are in cahoots and it's all a carefully-managed charade where they're playing both sides for maximum profit.
If either of those are true, then it seems unlikely that she'd mind too much what Trump says about George.
