During the January 27 interview, Trump asked Nieto to stop saying publicly that Mexico would not pay for the wall because he had placed Trump in a political connection. The expected costs are compounded by the cost of forced seizure of land under existing domain legislation. Secure Fence Act refunds have been costly; the average payment to landowners was $12,600, but payments were as high as the $1.1 million allocated to the conservation agency. And that cost does not include taxpayers` money spent on legal fees. While it is difficult to project the cost of lawsuits related to Trump`s proposed wall, they are likely to exceed the costs of convicting the Secure Fence Act, given the number of lands involved and the number of landowners involved. The deal has received bad reviews from some of Trump`s conservative allies. The quest for a spending deal has faced many obstacles, but it has always had strong support from the four congressional leaders, especially House of Representatives spokeswoman Nancy Pelosi, D-Calif. and top Republican Senate Mitch McConnell of Kentucky, two veterans of the appropriation process with a long history of compiling votes for the fund`s spending accounts. Their relationship has become entangled, but they are a powerful force when they unite. Critics of Trump`s plan say extending the wall would not prevent routine abuse of legal ports of entry by smuggling, transfer of travel visas, use of fraudulent documents or stowage.  They also point out that in addition to the misuse of import ports, a border wall could be bypassed by the construction of tunnels (comparing the borders of the Gaza Strip), the escalation or use of boats or aircraft.
     In addition, the impractable land along parts of the border may be more deterrent than a wall.  Trump spoke privately of staring at the wall with a water-filled ditch, inhabited by snakes or alligators, and electric fences crowned with lace capable of piercing human flesh.  Until it improves its acquisition planning and management, according to the DHS custodian, « any future initiative may take longer than expected, cost more than expected, and offer less capacity than expected to secure the southern border. » This bill sets a 5% tax for foreign transfers and increases the fee for the I-94 Departure form for various foreigners entering the United States, with a portion of the fee to be charged for border gates. On September 12, 2017, the U.S. Department of Homeland Security announced that Homeland Security Secretary Elaine Duke would waive « certain laws, regulations and other legal requirements » to begin building the new wall near Calexico, California.  The waiver allows the Department of Homeland Security, the National Environmental Policy Act, the Endangered Species Act, the Clean Water Act, the Clean Air Act, the National Historic Preservation Act, the Migratory Bird Treaty Act, the Migratory Bird Conservation Act, the Archaeological Resources Protection Act, the Safe Water Water Act, the Noise Control Act, the Solid Waste Disposal , the Antiquities Act, the Federal Land Policy and Management Act, The Administrative Procedure Act, the Native American Graves Protection and Repatri Act and the American Relingious Freedom Act.  Trump declared a national state of emergency in 2019, after the Democratic-led House of Representatives refused to provide more than $5 billion to fund the border wall and offered $1.4 billion to build fences in the Rio Grande Sector Valley.
