Don't think so. IIRC, they made a big deal of inviting Obamas to wedding but not Trumps.
I'd go more along the lines of Harry being led around by his dick and telling Markle stuff she's now wants to go public with. She's entrenched now, though, with media backing and will be hard to make go away.
It may be that Markle's gang wants to drag the rest of the Royals into the Andrew clusterfuck. Thus, Royals are in damage control.
Markle's a gold digger who wants to be queen or first lady somewhere, IMO. Trouble.
