(Washington, DC) -- House Democratic leader Nancy Pelosi asks, "Why are we at the brink again?" In a Capitol news conference, Pelosi accused House Republicans of provoking another crisis as a government shutdown looms next week. The feds run out of money early Tuesday morning without a bipartisan deal to extend funding. Many Republicans insist on defunding Obamacare as a condition for extending government spending. Pelosi called it a "Tea Party ransom" and said defunding the healthcare law is not going to happen. She argued that conservatives who run the House are banging their heads against the wall "at the expense of the country."
