Trump declares emergency over border wall - BBC News
The US president takes questions from reporters after his announcement at the White House.
The US president has announced he will use emergency powers to pay for a border wall with Mexico.

The rarely-used move would enable Mr Trump to bypass Congress, which has refused to approve the money needed.

Senior Democrats accused the president of a "gross abuse of power" and a "lawless act".

Several Republicans also voiced concern at the plan.
