You can see a lot more in Flynn Jr's twitter feed.
As CNN reported in mid-November, Flynn Jr routinely circulates conspiracy theories and makes racist comments of all sorts. Nor is this some tenuous guilt by association. The younger Flynn is not only his father's son. He is also his chief of staff and top aide at the security consulting firm Flynn has run since leaving the military. Indeed, in the fever swamps in which this conspiracy theory germinated and grew, Flynn has been cheered as the figure set to break open the truth about the (non-existent) Clinton/Podesta child sex ring.
Flynn will become the White House National Security Advisor in a month and a half.
