Connecting more dots:
Romney & Salinas were both in Harvard at the same time. Different schools –Salinas got master's degree in Public Administration in 1973 & a PhD from Harvard's Kennedy School of Government in 1978 and Romney got a JD/MBA in 1975.
No evidence found that they knew each other, but given Romney's family's history in Mexico, would it be a surprise if they didn't?
Citibank was involved in laundering $90 million out of Mexico to accounts in London & Switzerland for Raul Salinas in 1999. Alwaleed has been a large investor in Citi since 1991.
