First lawsuit filed challenging Trump's national emergency

Consumer advocacy group Public Citizen on Friday filed the first of what is expected to be a series of lawsuits challenging the legality of President Trump's emergency declaration, BuzzFeed News reports.

Details: Public Citizen is representing three Texas landowners and the Frontera Audobon Society, who have been told by the federal government that portions of Trump's proposed border wall would cross their properties. They argue that the president has exceeded his power under the federal National Emergencies Act — disputing that there is any immigration emergency whatsoever — and that Trump's declaration infringes upon separation of powers.
