I looked into loop capital.
Sec/iard and finra are 2 good sources.
They broker infrastructure/ muni deals. Well connected have a 150 brokers. They are connected to some of the construction companies. (Not kosher)
Loop has been fined for misleading filings on deals. (Things like revamping la guardian airport.)
Magic Johnson and Goldman Sachs have some connection, could be nothng...I dont recognize the other names .
