Donald Trump has warned he will shut down the US government if his Mexico wall is blocked.
The US President has attempted to secure funding to build the wall, which was a cornerstone foundation of his 2016 campaign.
The project will require roughly $1.6 billion and will cross 1,954 miles.
However, the plan to push it through has stalled in Congress, and faces an uncertain future in the US Senate.
Speaking in Arizona, Trump said if he had to shut down the government to build funds for the project, it would be done.
He insisted the American people voted for "total control" of their immigration and blasted the Democrats for putting "American security" at risk.
During his campaign, the US president had vowed he would ensure Mexico would pay for the wall along the US border, but the Mexican government has made clear in no uncertain terms this will not happen.
