When Washington took over the beleaguered mortgage giants Fannie Mae and Freddie Mac during the collapse of the housing market and the financial crisis of 2008, it was with the implicit promise that they would be returned to shareholders after being nursed back to health.

But now, with the unsealing of documents this week that were produced as part of a lawsuit filed against the government, new evidence is coming to light on how intimately the White House was involved in the Treasury’s decision in August 2012 to keep all the companies’ profits for the government. That move effectively maintained Fannie’s and Freddie’s status as wards of the state.

The newly released documents go beyond previous disclosures in the case and make clear that the Obama administration never had any intention of restoring Fannie and Freddie, which enjoyed implicit backing from the government before the takeover, to their status as stand-alone entities.

An email from Jim Parrott, then a top White House official on housing finance, was sent the day the so-called profit sweep was announced. It said the change was structured to ensure that the companies couldn’t “repay their debt and escape as it were.”
