Keith Olbermann has broken a story on McCain's National Campaign Co-Chair and economic advisor, Phil Gramm. Turns out Gramm was a Registered Lobbyist for the Swiss Bank UBS, which is tens of billions deep in the subprime crisis.
So while Gramm was advising McCain to let people lose their homes rather than get more favorable terms on their loans, he was active as a lobbyist for UBS, which had a LOT to gain.
While UBS de-registered Gramm as a lobbyist on April 18th, this was about a month after McCain rolled out his plan regarding the supprime mortgage crisis, as Josh points out at TPM. And Gramm still serves as UBS vice Chairman.
