President Donald Trump has now laid out exactly what he wants in the “big, beautiful wall” that he’s promised to build on the US-Mexico border. But his effort to build a huge barrier to those attempting to enter the US illegally faces impediments of its own.
It’s still not clear how Trump will pay for the wall that, as described in contracting notices, would be 30 feet (9 meters) high and easy on the eye for those looking at it from the north. The Trump administration will also have to contend with unfavorable geography and many legal battles.
A look at some of those obstacles:
Trump promised that Mexico would pay for his wall, a demand Mexico has repeatedly rejected. Trump’s first budget proposal to Congress, a preliminary draft that was light on details, asked lawmakers for a $2.6 billion down payment for the wall. An internal report prepared for Homeland Security Secretary John Kelly estimated that a wall along the entire border would cost about $21 billion. Congressional Republicans have estimated a more moderate price tag of $12 billion to $15 billion. Trump himself has suggested a cost of about $12 billion.
It’s unclear how much money Congress will approve. Lawmakers have been balking at his plans to sharply cut other federal spending to pay for the wall and other boosts to border security, while increasing military spending. White House spokesman Sean Spicer told reporters this past week that the administration was still looking at how the wall would be funded, adding that it has not given up on Mexico footing the bill.
Roughly half of the 2,000-mile (3,200-kilometer) US-Mexico border is in Texas and marked by the winding and twisting Rio Grande. A 1970 treaty with Mexico requires that anything built near that river not obstruct its flow. The same treaty applies to a stretch of border in Arizona, where the Colorado River marks the international boundary.
Some fencing that is already in place along the frontier is built well off the river, in some places nearly a mile (about a kilometer) away from the border.
Trump will have to navigate not only the treaty maintained by the International Boundary and Water Commission but also various environmental regulations that protect some stretches of border and restrict what kind of structures can be built and where. The contracting notices of March 17 say the Trump administration wants the wall dug at least 6 feet (almost 2 meters) into the ground.
Nearly all of the land along the Texas border is privately held — much of it by people whose families have been in the region for generations — and buying their land won’t be easy, as Presidents George W. Bush and Barack Obama discovered. Lawyers for both administrations fought in court with private landowners. Obama’s efforts to buy privately held land in the Rio Grande Valley have carried over into Trump’s term.
The Trump administration appears to be preparing for the legal fight and included a request for more lawyers to handle such cases in its budget proposal. Spicer said this past week the administration would “take the steps necessary” to fulfill Trump’s promise to secure the southern border.
Meanwhile, the Catholic Archdiocese of Mexico said on Sunday that Mexicans who help build Trump’s border wall would be acting immorally and should be deemed traitors. In a provocative editorial, the country’s biggest Archdiocese sought to increase pressure on the government to take a tougher line on companies aiming to profit from the wall, which has strained relations between Trump and the Mexican government.
“Any company intending to invest in the wall of the fanatic Trump would be immoral, but above all, its shareholders and owners should be considered traitors to the homeland,” said the editorial in Desde la fe, the Archdiocese’s weekly publication.
On Tuesday, Economy Minister Ildefonso Guajardo warned firms it would not be in their “interests” to participate in the wall.
But the editorial accused the government of responding “tepidly” to those eyeing the project for business. A spokesman for the Archdiocese, which centers on Mexico City and is presided over by the country’s foremost Roman Catholic cleric, Cardinal Norberto Rivera, said the editorial represented the views of the diocese.
The Desde la fe editorial, which was published online, said the barrier would only feed prejudice and discrimination. “In practice, signing up for a project that is a serious affront to dignity is shooting yourself in the foot,” it wrote.
Mexican cement maker Cemex has said it is open to providing quotes to supply raw materials for the wall but will not take part in the bidding process to build it. Grupo Cementos de Chihuahua, another company specializing in construction materials, has also signaled readiness to work on the project.
