A massive caravan of immigrants seeking asylum began moving towards the US through Mexico in Autumn 2018, which the US president characterised as a crisis and vowed to build a wall on the US-Mexican border.
After forcing the longest government shutdown in history over his demand for $5 billion in border wall money, Mr. Trump a year ago relented and signed a spending bill with only $1.375 billion.
The Trump Administration has marked the 100th mile [160th kilometre] of wall construction along the southern border of the country, Fox News reported, citing Department of Homeland Security Secretary Chad Wolf.

Last year, Trump declared he would divert $3.6 billion from the Defense Department's military construction budget and $2.5 billion from the Pentagon's drug-interdiction budget to build his wall.
A lower court in El Paso, Texas had temporarily blocked the funds before the injunction was lifted.
In essence, Trump's declaration enabled him to draw billions more dollars beyond the $1.3 billion that Congress specifically authorized for border wall funding.
The White House said it will consider migrants to be a burden if they aren't covered by approved health insurance within 30 days of entering the United States or don't have the financial resources to cover "reasonably foreseeable medical costs".More news: Laura Whitmore reveals Love Island has been overshadowed by Caroline Flack's arrest
The ruling comes as a rare victory for the president, who has faced repeated legal barriers in his efforts to crack down on irregular immigration at the border since taking office.
Building a wall along the border with Mexico was one of the central proposals of his immigration plan when running for president, and it is a policy the president still often cites to fire up crowds at rallies.
He cheered Wednesday's night's ruling by the New Orleans-based court with a tweet, writing: "Entire Wall is under construction or getting ready to start!" The lawsuit was filed by El Paso County, Texas, and the Border Network for Human Rights.
As of December, on official federal projects, Customs and Border Protection has updated roughly 86 miles of existing barrier, swapping out old, dilapidated designs with a newer system.More news: Angela Merkel and Vladmir Putin push ahead with pipeline
"We're confident the district court's ruling that the president can't usurp Congress's power on this spending decision is correct", said Kristy Parker, a lawyer for the Protect Democracy Project, which is representing groups that sued the administration.
