The White House on Tuesday said President Obama would veto GOP-backed spending bills that would keep some parts of the government open but still deny funding for Obamacare.

"These piecemeal efforts are not serious, and they are no way to run a government,” White House spokeswoman Amy Brundage said. “If House Republicans are legitimately concerned about the impacts of a shutdown — which extend across government from our small businesses to women, children and seniors — they should do their job and pass a clean CR to reopen the government.”

Although the Democratic-controlled Senate has declared such bills dead on arrival, Brundage made clear that Obama would veto the measures if they arrived on his desk.

Republican House leaders are uniting behind a plan that would fund national parks and other popular programs closed by the government shutdown. The goal is to do so without providing the money needed to keep Obamacare running.

House Speaker John Boehner's, R-Ohio, office immediately blasted Obama's veto threat.

"How does the White House justify signing the troop funding bill, but vetoing similar measures for veterans, national parks and District of Columbia?" asked Boehner spokesman Michael Steel. "The president can't continue to complain about the impact of the government shutdown on veterans, visitors at national parks and D.C. while vetoing bills to help them."

In the final moments before the government shutdown, Obama signed a bill that kept military pay flowing despite the lack of a continuing resolution.

The latest round of finger pointing in no way closes the massive divide between Republicans and Democrats, essentially guaranteeing the government shutdown will stretch into a second day, if not longer.
