Article does briefly point out that people were enticed ("arm-twisted") to make political donations to get in on a "deal of the century" - a no-lose proposition with 20% a shot up to three times a year.
It may be difficult to prove that there are security violations on Hillary's part, unless she specifically directly endorsed Hsu's "enterprises" and encouraged "investment" in them, rather than by calling Norman "her friend" she may have implicitly landed the "air" of respectability and trust on him. I think "holding him out" would be the equivalent legal term for case to be made.
I think Earvin "Magic" Johnson and few other athletes and famous people were paid "endorsers" in a "phony investment" scheme some years ago, but endorsers were not charged in the participation in the fraud. As an aside, Hillary (as Bill Clinton before) had several fundraisers with Magic Johnson.
There is no question that both Hsu and Hillary profited from this symbiotic relationship and the scheme, but I am not sure that securities fraud on her part can be proven, unless she slipped up in her "endorsements". I think better question to ask is, exactly which accomplishments caused Norman Hsu become a board member of American School (the beginning of "respectability tour" for Hsu,) i.e. WHO recommended him to the post - that's where the thread could start to unravel - but that maybe on a par with that other question - WHO hired Craig Livingstone? Did not see any curiosity from the media regarding this, and there may be a guy who could be willing to talk - Bob Kerrey, who is NOT going to run for Senate from Nebraska, partly because of association with American School.
American School and its foundations, in part, may also be a conduit for "funny money".
