President Obama will appear before business leaders on Wednesday to warn Republicans of the economic consequences of a government shutdown.
“Republicans need to do the job voters asked them to do” and prevent a government shutdown, Earnest said Tuesday.
Republicans and Democrats on Capitol Hill are locked in a stalemate over a budget agreement to keep the government open ahead of a Sept. 30 deadline to pass spending bills.
Obama and his Democratic allies say they will not accept funding bills that keep sequestration spending caps in place. But Republicans are wary of raising spending levels, especially during in the midst of the 2016 presidential race.
Further complicating negotiations, a group of conservative lawmakers in the House of Representatives has pledged to oppose any spending bills that fund Planned Parenthood.
Planned Parenthood has been caught in a controversy over its fetal tissue donations, following the release of videos detailing the program.
The White House has cast doubt on the authenticity of the heavily edited videos and has said it would not support stripping federal funding from Planned Parenthood.
