President Barack Obama should take “immediate and dramatic action” to save the U.S. Postal Service from insolvency, Senator Thomas Carper, a Delaware Democrat, told him in a letter.

The service, which says it will run out of cash within a year without relief from laws governing it, must make changes akin to what the U.S. auto industry did two years ago, Carper said yesterday in a letter to Obama. The service needs help from the White House to do so, wrote Carper, the chairman of a Senate subcommittee overseeing the service.
