Since Flake is in news via Romney, I did a little more digging and found Flake's connections Saudi wealthy families and businesses.
Don't know if this is old news or not.
First, Searching on Flake's early days since his days as Rep. Flake from AZ, shows that he has been an advocate for opening relations with Cuba.
One businessman who clearly wanted free, unrestricted trade re-opened with Cuba was John Parker Wright, IV, who is not only a Naples, FL cattle producer, but has very strong ties to Saudi Arabia and China.
Flake was working for Saudi Arabia and China!
