A federal judge on May 24 blocked construction of Donald Trump's border wall, ruling that Trump cannot use a "national emergency" to take money from government agencies for the barrier. Judge Haywood Gilliam of the US District Court for Northern California ruled that the diversion of the money, largely from the US military, likely oversteps a president's statutory authority. The injunction specifically limits wall construction projects in El Paso, Tex., and Yuma, Ariz. Gilliam quoted Mick Mulvaney, the acting White House chief of staff, who said in a TV interview the wall "is going to get built, with or without Congress." The judge said presidential action "without Congress," when legislators refuse a funding request from the White House, "does not square with fundamental separation of powers principles dating back to the earliest days of our Republic."

Despite his boast to have "ended" the drug war and pledge to explore cannabis legalization, Mexico's new populist president is seeking to create a special anti-drug "National Guard" drawing from the military and police forces. This plan is moving rapidly ahead—and the military is still being sent against campesino cannabis growers and small traffickers.

Joaquín "El Chapo" Guzmán, infamous kingpin of Mexico's Sinaloa Cartel, was unanimously found guilty on all 10 counts against him by a federal jury in Brooklyn, New York, on Feb. 12. He was convicted of overseeing an international criminal conspiracy to import tons of cocaine, heroin, methamphetamine and marijuana into the United States over a 20-year period, and laundering the billions of dollars in proceeds.

Two months into his term, Mexican President Andrés Manuel López Obrador declared an end to his country's "war on drugs," announcing that the army would no longer prioritize capturing cartel bosses. The new populist president made his declaration Jan. 30, at the end of his second month in office. He told gathered reporters at a press conference that the "guerra contra el narcotráfico," launched in 2006 by then-president Felipe Calderón, has come to and end. "Officially now, there is no war; we are going to prusue peace," he said.

A 16-state coalition filed a lawsuit against President Donald Trump's administration on Feb. 18, requesting the court to issue a judicial determination that Trump's national emergency declaration over the southern border wall is unconstitutional. California Attorney General Xavier Becerra announced the lawsuit, stating: "Unlawful southern border entries are at their lowest point in 20 years, immigrants are less likely than native-born citizens to commit crimes, and illegal drugs are more likely to come through official ports of entry. There is no credible evidence to suggest that a border wall would decrease crime rates."

Under pressure to address the ongoing wave of targeted assassinations in Colombia, President Iván Duque Jan. 30 for the first time spoke before the National Commission to Guarantee Security, formed by the previous government to address continuing violence in the country—which has only worsened since he took office last year. Duque said 4,000 people are now under the government's protection program for threatened citizens. But his office implied that the narco trade is entirely behind the growing violence. Interior Minister Nancy Patricia Gutiérrez told the meeting: "This great problem is derived from the 200,000 hectares of illicit crops that we have in Colombia." (Espectador, Jan. 30)

World oil prices remain depressed, now hovering at around $60 per barrel, although they did experience an uptick this month, probably driven by the escalating crisis in Venezuela and fears of a US-China trade war. (Xinhua, Jan. 27; OilPrice, Jan. 18) Yet this month also saw Zimbabwe explode into angry protests over fuel prices. A three-day nationwide strike was declared by the trade unions, and the government responded with bullets and a total Internet shut-down. At least 12 were killed and hundreds arbitrarily arrested. The unrest was sparked when the government doubled fuel prices, making gasoline sold in Zimbabwe the most expensive in the world. President Emmerson Mnangagwa said the price rise was aimed at tackling shortages caused by an increase in fuel use and "rampant" illegal trading.

Carlos Ruiz Massieu, head of the UN Mission in Colombia, warned President Iván Duque about the human rights situation in the country when they met at the Casa de Nariño presidential palace in Bogotá last week. Ruiz said he especially expressed convern about "the issue of the assassinations of social leaders and human rights defenders." (Nuevo Siglo, Jan. 15) Duque had days earlier announced a new plan of action to address the ongoing targeted assassinations, pledging: "We are going to strengthen all the instruments that the Public Force has at its disposition so that the leaders of armed groups, which are behind a large part of these homicides, are brought to justice." He spoke at Riohacha, La Guajira department, one of the areas hard hit by the ongoing killings. (Nuevo Siglo, Jan. 10)
