At the same time, the founders and employees of Mason Capital Management, a $13.6 billion New York hedge fund, have become leading contributors to Paul's political aims. The hedge fund has offices in London and San Francisco and offers clients offshore investments through a limited partnership in the Cayman Islands, among other strategies.
Company co-founder Kenneth Garschina has also given $250,000 -- the single-biggest contribution -- to America's Liberty PAC, a so-called super political action committee run by longtime supporters of Paul. He has contributed $15,100 directly to Paul's campaign or to funds the senator controls. Michael Martino, Garschina's co-founder, has given $12,600 to Paul's campaign and funds.
