Good grief, not everything is nefarious or requires a tin foil hat. Westerhout was highly recommended by the RNC at a time when 98 percent of WDC was a NeverTrumper and loathe to work for the new President or his administration.
As for Romney, don't give him more credit and stature than he's worth. Ronna McDaniel, Chair of the RNC, is Romney's niece and is doing an admirable job for the Committee, the President and his administration. She has even spoken out against her uncle on several occasions through the years.
Westerhout served the President very well since Jan 20, 2017. I think if POTUS had his druthers he would have reprimanded her for talking to the press, even "off the record" and especially while enjoying some wine, and let her stay in the position. But she pissed on the third rail .... his family. She tied his hands and had to go.

While Madeleine Westerhout has a fully enforceable confidentiality agreement, she is a very good person and I don’t think there would ever be reason to use it. She called me yesterday to apologize, had a bad night. I fully understood and forgave her! I love Tiffany, doing great!
