"Issa-Ross #Postal act only bill in Congress to #saveUSPS financial crisis w/o taxpayer bailout," tweeted @GOPoversight.

The committee staff added a shot at Democratic committee member Rep. Gerry ConnollyGerald (Gerry) Edward ConnollyTrump EPA eases standards for coal ash disposal Overnight Energy: Fewer than half of school districts test for lead | Dems slam proposed changes to Endangered Species Act | FEMA avoids climate change when discussing plan for future storms Overnight Energy: EPA watchdog won’t drop Pruitt probes | Exxon leaves conservative advocacy group | Lawmakers offer changes to Endangered Species Act MORE (D-Va.): ".@OversightDems & @GerryConnolly are spreading a lot of #Postal myths #saveUSPS"

The Democratic account returned fire with a shot from ranking member Elijah Cummings (D-Md.): "Cummings re:Issa/Ross bill: Is the [committees] responsibility 2 consider bills that have a chance 2 become law this bill doesnt meet that test."

Connolly also defended himself with a tweet: "Chairman [Dennis] Ross [(R-Fla.), of the subcommittee that oversees the postal service] offers false choice on #USPS. [Reps. Stephen] Lynch [(D-Mass.)] and Connolly bills allow new model and innovation for #postal service #InnovateUSPS."

The dueling hashtags used by the Republican and Democratic members of the committee refer to the Issa-Ross Postal Act (#saveUSPS) and the Democratic proposal introduced by Cummings and Lynch, the Innovate to Deliver Act (#InnovateUSPS), respectively.

Issa-Ross would raise premiums for USPS employees to be in line with other federal workers and allow the Postal Service to raise prices, according to a website set up by Republican committee members, savingthepostalservice.com. If the Postal Service fails to pay its bills, the Republican plan would put it under control of an independent watchdog empowered to restructure labor agreements.

The Democratic plan focuses on innovation to bring the Postal Service into financial safety. It would expand its services to check-cashing, facility leasing and retail services, create a new chief information officer and correct over payments to retirement accounts.

The Postal Service is expected to hit its $15 billion borrowing limit in a matter of weeks if no action is taken.
