It is possible. At times it did seem that HH was vying for attention and maybe trying to compete with Melania. I don’t see Melania being so petty tas o oust her.
Considering the timing, it does seem that it was Trump’s idea, pissed because of her testimony — the day after, IIRC.
I thought she wanted out - was it confirmed that Trump told her to leave? If she had wanted to stay she probably should have had a more demure image for herself.
I wondered if she was competing with Melania...she lightened her hair, etc. I thought she looked better with her natural dark hair.
