President-elect Donald Trump has warned that the federal government could be headed for a shutdown. "If you are going to shut down the federal government, shut down now," Trump said. "Because the public, which has the power to change things, just like they had the power to get the Republicans in Congress, and they had the power to get the Republicans in the presidency, they are angry." A government shutdown would have a significant impact on the U.S. economy, as well as on the lives of millions of Americans who rely on government services. Trump has not specified what would trigger a shutdown, but he has said that he is prepared to let it happen if necessary. Congressional Republicans have said that they are not interested in a shutdown. However, they are divided on how to fund the government, and it is possible that they could fail to reach an agreement before the current funding deal expires on April 28. If the government does shut down, it would be the first since 2013.
