Earlier this month, two former Treasury Secretaries and a former chairman of the Federal Reserve appeared in court to defend decisions they made more than six years ago. They were called to testify in a lawsuit brought by former AIG CEO Maurice "Hank" Greenberg. Greenberg, who built AIG into the world's biggest insurer before leaving in 2005, is suing the U.S. government over the $180 billion bailout package it was given in September of 2008. This week, the government will present its defense. Greenberg claims the bailout essentially trampled the rights of AIG shareholders and that the big banks got bailed out on less onerous terms than AIG did. Greenberg's investment company Starr International was the biggest AIG shareholder at the time. There are several lawsuits stemming from the U.S. government's bailout of Fannie Mae and Freddie Mac as well. Fannie Mae and Freddie Mac, both government-sponsored entities, were put into conservatorship by the government during the financial crisis.
