A House Appropriations Subcommittee hearing featuring two low-profile cabinet members won’t make a splash even on a slow-news day, and certainly not when a juicy story like the AIG outrage has so many angles to explore.

But take my word for it: big news came out of yesterday’s Congressional testimony by Department of Housing and Urban Development (HUD) Secretary Shaun Donovan and Department of Transportation (DOT) Secretary Ray LaHood. The cabinet secretaries announced

a new partnership to help American families gain better access to affordable housing, more transportation options, and lower transportation costs. The average working American family spends nearly 60 percent of its budget on housing and transportation costs, making these two areas the largest expenses for American families. Donovan and LaHood want to seek ways to cut these costs by focusing their efforts on creating affordable, sustainable communities.

I explain why this is important and welcome news after the jump.
