GreenPoint Mortgage, the latest casualty of the mortgage meltdown, was once overseen by a director of Freddie Mac, the giant public company chartered by Congress to bolster home lending.

Thomas S. Johnson was elected to Freddie Mac’s board in 2004 when he was CEO of GreenPoint Financial, then parent of GreenPoint Mortgage. That year, GreenPoint Financial was acquired by North Fork Bancorp for $6.3 billion. Capital One acquired North Fork last year for $13.2 billion.
