President Donald Trump on April 22 signed an executive order suspending the admission of new permanent residents into the United States for the next 60 days, with an option for renewal, citing "a potentially protracted economic recovery with persistently high unemployment if labor supply outpaces labor demand." The order bars the entry of several categories of immigrants who are currently outside of the US and do not already have a valid immigrant visa to enter the country. This includes those seeking green cards for work, with certain exceptions, as well as the spouses and children of legal permanent residents or green-card holders, and the siblings, parents and adult children of US citizens.

Some 60,000 asylum-seekers sent back by the United States to Mexico until their claims can be heard in US courts face a longer wait in Mexican limbo after the US Supreme Court issued an order on March 11 that allowed a controversial anti-immigration policy to stand. An appeals court in San Francisco had ruled that the policy—officially called the Migrant Protection Protocols, but known as "Remain in Mexico"—was unlawful in the two border states under its jurisdiction: Arizona and California. The new order means asylum-seekers must now pin their hopes on the outcome of an expected formal appeal by President Donald Trump's administration—but that might not play out through the courts until early 2021.

Mexican lawmakers are predicting legal cannabis by month's end, and portraying it as a key to de-escalating the endemic narco-violence. But national headlines are full of nightmarish cartel violence—making all too clear how big the challenge will be.

There were scenes of chaos in Mexico's northern border towns Feb. 29 in response to rulings in rapid succession by a US federal appeals court on the Trump administration's "Remain in Mexico" policy. First, the Ninth Circuit Court of Appeals in San Francisco ruled against the administration's policy, (euphemistically dubbed the Migrant Protection Protocols) that forces migrants and refugees seeking asylum to wait in Mexico while their claims are reviewed, and severely limits the number of migrants eligible for asylum. Thousands of asylum-seekers who had been camped out for weeks in Matamoros, Ciudad Juárez, Nogales and Tijuana immediately amassed at the border crossings, hoping to gain entry to the US. But the crossings were closed, and hours later, the Ninth Circuit granted an emergency stay on the injunction, as requested by the administration, effectively reinstating the MPP while further arguments are heard. The gathered migrants were dispersed by Mexican security forces.

Three groups filed suit against the Trump administration on Feb. 29 in federal court over the administration's diversion of funds allocated to the Department of Defense for border wall construction. The Trump administration has announced its plan to use $3.6 billion in military construction funds and $2.5 billion in other military funds for wall construction. The administration is attempting to use these funds despite Congress' exclusive appropriation of $1.375 billion for border wall construction under the Consolidated Appropriations Act of 2019. When President Trump signed the CAA into law, he also issued Proclamation 9844, declaring a national emergency along the southern border. The American Civil Liberties Union (ACLU), Sierra Club, and Southern Border Communities Coalition sued, asking the US District Court for the Northern District of California to block the diversion of the funds. They claim that as Congress did not appropriate the funds for border wall construction, the president's actions usurp the constitutional budget allocation powers of the Legislative Branch.

More than 3,000 farmers and residents of four rural municipalities in Mexico's northern state of Chihuahua clashed with Mexican National Guard troops on Feb. 4 in a protest over the federal government's plan to divert water from a dam into the Rio Grande for the use in the United States. Protesters from the municipalities of Camargo, La Cruz, Delicias and San Francisco de Conchos confronted troops guarding La Boquilla Dam on the Rio Conchos with the aim of occupying the facility and preventing the water diversion. The National Water Commission (Conagua) intends to open the sluices of the dam to divert hundreds of millions of cubic meters of water to the Rio Grande, in order to comply with a 1944 Water Treaty between Mexico and the US. Mexico has a 220-million-cubic-meter "water debt" to the US, but farmers say that the massive diversion will leave them with insufficient water.

President Trump plans to divert $7.2 billion from the Pentagon to go toward border wall construction this year, a sum five times greater than what Congress authorized in the 2020 budget last month, the Washington Post reported Jan. 13. This marks the second year in a row that Trump has sought to redirect money to the planned border wall from military construction projects and counter-narcotics funding. The administration will take $3.7 billion from military construction and $3.5 billion from counter-narcotics programs, according to figures obtained by the Post, compared to $3.6 billion and $2.5 billion last year, respectively.

A judge for the US District Court for the Western District of Texas issued a preliminary injunction Oct. 11 against President Donald Trump's proposed plan for funding the border wall, finding that it exceeds executive branch authority under the Appropriations Act. Trump issued a proclamation in February declaring a national emergency on the southern border of the US, as both a humanitarian and security crisis. El Paso County, Tex., and the Border Network for Human Rights sued to challenge the proclamation. Going further than previous rulings against the border wall plans, Judge David Briones specifically declared Trump's emergency proclamation to be "unlawful."  (Jurist, Politico, Oct. 11)
