Why has Trump been showing so much support for Ghislaine Maxwell?

Because he's a bad guy who supports sexual assault. It's been confirmed ever since that bus tape revealed to the public a few years ago.

he knows that she knows . trumps blood pressure must be off the charts .

He wants her to let her guard down so Barr can murder her easier than he did Epstein.

She looked the other way as tRump & Epstein had $ex with underage boys + girls 

.. One of them named Ivan(ka).

Maybe she also has a couple peepee tapes too!

Really?  How so?  State your sources or STFU.  (If you know how).

He may need a new friend after the election.

He'd very much appreciate if she'd refrain from implicating him for his involvement in child slavery.
