| The dialogue about the impeachment starts near the beginning.
| Having Biden in the White House is as good as Trump or anyone
| else in their organization. Obviously Schiff and Nadler pledged
| their allegiance to the organization by raping boys on the
| record, with their task being to drag out an impeachment designed
| to obstruct and delay any real efforts to remove the President,
| thus keeping Trump in power. The witness blocking was to cause an
| apparent uproar delaying things with legal actions until late
| Summer. Soon after, the President would resign, leaving any other
| candidate with not enough time or support to compete with an
| opportunistic Biden, who is as good as Trump or any other
| Illuminati friendly politician in the Presidency.

|
| See the latest PDF updates: FBI Director Wray, AG Barr, SoD

| rape and kill about two dozen boys by 6:00 am. Muir starts around
| 5.15am, then Holt about 5:38 am. Multi-billionaire Rupert
| Murdoch, owner of News Corp and also Fox Corporation, takes his
| turn after Holt. Video links below:

| million dollars. He is informed by group members that there are
| enough people for the event already and his participation is not
| necessary. At 1634 McConnell states "I fucked 15 kids, how am I
| not getting paid by you?" He is dismissed by Donald Reeves with
| "I think that will be all Mr. McConnell."
