WASHINGTON, U.S. - Donald Trump’s most controversial campaign promise - the Mexico border wall to fight illegal immigration has led to wide protests in both Mexico and the U.S.
However, the President started making concrete plans to build the contentious wall from the word go and even demanded that Mexico pays for the wall.
Now, the U.S. President has said that the proposed wall along the U.S.-Mexico border must be see-through to prevent “sacks of drugs” landing on people's heads.
He quipped, “They hit you on the head with 60 pounds of stuff? It's over.”
Trump estimated "anywhere from 700 to 900 miles" of barricades were needed between the two countries, with mountains and rivers providing "natural barriers" along the rest of the 2,000-mile frontier.
The frontier stretches across four U.S. states and already has 600 miles of fences and walls, although the President admits some some areas need replacement or repair.
Trump, who spoke to reporters on board Air Force One from Washington o Paris, said that it was vital that border agents could see through the wall to be aware of oncoming dangers.
He reportedly said, “One of the things with the wall is you need transparency. You have to be able to see through it. So it could be a steel wall with openings, but you have to have openings because you have to see what's on the other side of the wall. As horrible as it sounds, when they throw the large sacks of drugs over, and if you have people on the other side of the wall, you don't see them. They hit you on the head with 60 pounds of stuff? It's over."
He said the idea may be a little ‘crazy’ but said he was concerned someone would be injured.
The President added "violent and vicious" rivers provided a natural barrier along parts of the border.
Trump said, "You have mountains. You have some rivers that are violent and vicious. You have some areas that are so far away that you don't really have people crossing. But you'll need anywhere from 700 to 900 miles."
The White House, that initially started that Trump's comments were off the record, but later changed course and released his remarks.
Mexico's former deputy foreign minister, Andres Rozental said the proposed see-through wall was "the most ridiculous thing I have heard in many, many years. It just doesn't make any sense."
The proposed border wall and Trump’s subsequent and repeated vow to make Mexico pay for it has strained ties between the neighbors.
Trump has insisted that while the Congress would need to fund the wall at first, he would find a way for Mexico to repay the U.S. for the construction.
