Republicans on Capitol Hill want to use the 2016 federal budget to blow up the US government's new open internet policy—and now the White House is pushing back.

The Obama administration has "serious concerns" about "highly problematic ideological riders" aimed at "delaying or preventing implementation of the FCC's net neutrality order," according to a letter to Congress dated Tuesday and signed by Shaun Donovan, director of the Office of Management and Budget. The OMB is the executive branch's budget office.

Among those concerns are three provisions that would effectively kill the Federal Communications Commission's new open internet rules, which went into effect last Friday. Those rules are designed to ensure that broadband providers treat all internet data equally.

The White House response, while not quite a veto threat, is a clear warning to GOP lawmakers that the administration is willing to challenge their budget tactics.
