Washington: President Donald Trump, citing an "invasion" of drugs and criminals, declared a national emergency at the US-Mexico border on Friday to fund construction of his long-sought wall, a move slammed by Democrats as an unlawful "power grab."
Trump's extraordinary step will enable him to bypass congressional opposition and seek to redirect billions of dollars in federal funds to build the wall — delivering on a key election promise to his right-wing base.
"We are going to confront the national security crisis on our southern border and we are going to do it one way or the other," Trump told reporters in the Rose Garden of the White House.
"I am going to be signing a national emergency," said the US leader. "We are talking about an invasion of our country, with drugs, with human traffickers, with all types of criminals and gangs."
Trump's decision to resort to emergency powers -- after a bitter standoff with Democrats blocking his wall project culminated in a 35-day government shutdown — has alarmed lawmakers, including in his Republican Party, who warn it sets a dangerous precedent.
The declaration came after the president agreed to a massive bipartisan spending measure that averts the possibility of a second crippling shutdown.
But House Speaker Nancy Pelosi and Senate Minority Leader Chuck Schumer, the Democratic leaders in Congress, immediately denounced a "power grab" by a president "who has gone outside the bounds of the law" to fund his 2016 campaign pledge to build the wall.
New York State's attorney general, Letitia James, announced the first of what were expected to be a slew of legal challenges, warning a national emergency without legitimate cause could create a constitutional crisis, and vowing to "fight back with every legal tool at our disposal."
Trump said he fully expected to be challenged in court — but voiced confidence he would prevail.
"Look, I expect to be sued," he said bluntly. "Sadly it will go through a process and happily, we'll win, I think."
Trump's announcement, which opens a new confrontation with lawmakers and creates risky legal peril, comes after he reluctantly agreed to a measure keeping federal agencies operational through September 30 -- but without the funding he sought for a border wall.
That deal caps a two-month battle over border money which Democrats are widely seen as having won.
Trump has long demanded $5.7 billion to build portions of a wall on the 2,000-mile (3,200-kilometer) southern border. But Congress provided just $1.375 billion for border barriers, and not specifically a wall, in the bill.
Under the National Emergencies Act, the president can declare a national emergency, providing a specific reason for it.
That allows the activation of any of hundreds of dormant emergency powers under other laws, which can permit the White House to declare martial law, suspend civil liberties, expand the military, seize property and restrict trade, communications and financial transactions. Recent Presidents — and Trump too — have used emergency powers on such issues.
