Plans to fund a border wall at the U.S.-Mexico border are troubling D.C. politics. During his campaign for the presidency, candidate Trump promised a wall would be built to reduce security issues he associated with existing border policy. In the longest government shutdown in history, Democrats in Congress refused President Trump’s demand for $5.7 billion in funding for such a wall. While the government eventually reopened, ongoing negotiations in Congress to reach a border security deal ahead of another shutdown seem unlikely to reach an agreement that will please the President. In the meantime, troops have been deployed to stop a so-called migrant caravan from crossing the border while anti-wall rallies are held only a mile away.
