The US government has shutdown due to Congress failing to agree on a budget by the September 30th deadline. This has resulted in nearly 1 million government employees and contractors being furloughed without pay. The main issue causing the shutdown is disagreement over the Affordable Care Act (Obamacare) between Republicans, who want to defund it, and Democrats, who want to allow it to continue as is for now. If a resolution is not reached soon, Republicans may use an upcoming vote on raising the debt ceiling as another opportunity to oppose Obamacare.
