WASHINGTON (AP) — The American Civil Liberties Union says it will file a lawsuit challenging President Donald Trump’s emergency declaration to fund a wall on the U.S.-Mexican border.

The Friday announcement came hours after Trump signed the declaration and said he expected legal challenges. The civil rights group will argue that Trump’s use of emergency powers is unprecedented and can’t be used to build a border wall.

ACLU Executive Director Anthony Romero says the declaration is ‘patently illegal.’ Their legal action would be separate from anything Congress may do.

House Speaker Nancy Pelosi (puh-LOH’-see) and Senate Minority Leader Chuck Schumer have also raised the possibility of legal action. They say Trump’s decision would “shred the Constitution” by usurping Congress’ power to control spending.

White House officials say some of the money would come from military construction projects.

WASHINGTON (AP) — President Trump says he’ll declare national emergency, use executive powers to bypass Congress, obtain more money for border wall.

Trump said Friday he will use executive powers to bypass Congress, which approved far less money for border barriers than he had sought. Trump plans to siphon billions of dollars from federal military construction and counterdrug efforts for his long-promised U.S.-Mexico border wall.

The move is already drawing bipartisan criticism on Capitol Hill and is expected to face rounds of legal challenges.

Trump says many other presidents have declared national emergencies. But the presidents he has cited did not use emergency powers to pay for projects that Congress wouldn’t support.

Emergency declarations by former presidents Barack Obama, George W. Bush and Bill Clinton were overwhelmingly for the purpose of addressing crises that emerged abroad. Many blocked foreign interests or terrorist-linked entities from access to funds. Some prohibited certain imports from or investments to countries associated with human rights abuses.

A list compiled by the Brennan Center says Clinton declared 17 national emergencies, Bush 13 and Obama 12.
