Trump's wall 'emergency' likely to face pushback

US President Donald Trump's announcement on Friday that he will declare a national emergency in order to build a wall along the Mexican border appears likely to face strong political pushback.

Democrats and some Republicans oppose an emergency declaration.

The US House of Representatives on Thursday night passed legislation on spending and border security to avert another government shutdown, hours after the bill was approved by the Senate. The budget bill allows for $1.37 billion in funding for 55 miles of border barriers.
