Standard & Poor’s Financial Services LLC is demanding that the Justice Department and former Treasury Secretary Timothy Geithner turn over more documents, including communications with President Barack Obama, in the U.S. government’s $5 billion lawsuit against the ratings agency.

The Justice Department sued S&P for allegedly inflating ratings for residential mortgage-backed securities and other high-risk investments before the 2008 financial crash. S&P has alleged that the Justice Department brought the case in retaliation for its downgraded credit rating of the United States.
