B&M Obama have not made a non-automated post on facebook or twitter since the 8th. You can tell automated posts because they have exact times and no relevant context (Happy birthday, happy MLK day, etc).
I just noticed that Oprah's twitter is the same way.
NO WAY IN HELL SHE WOULD NOT MENTION A TRUMP IMPEACHMENT. No way they would not promote the inauguration, and absolutely no way any of those personalities would go two weeks without bitching about Trump!
So who else is missing?
I think Hillary and Pelosi are likely arrested already too, despite the fact their pages are still posting. They have staff that could do that.
What's your source on the others?
The few times we've seen Pelosi last week she was being escorted by a bunch of women LEOs as well, usually you only send a team all the same sex as the target when an arrest is being made and they'll need to be searched.
I just haven’t noticed any mention of the others over time. ValJar last I heard had moved in with Obama in kalorama, Tony podesta dropped off the media scope just after POTUS was inaugurated and the others were the same.
