The Trump administration has seriously turned up the heat on Venezuela, slapping sanctions on the country's vice president as a drug "kingpin." The Treasury Department's Office of Foreign Assets Control (OFAC) on Feb. 13 officially named Tareck Zaidan El Aissami as a "Specially Designated Narcotics Trafficker" under terms of the Foreign Narcotics Kingpin Designation Act (Kingpin Act) of 1999. The order charges that El Aissami received pay-offs from a trafficking network linked to Mexico's Zetas narco-gang. Under the order, US nationals and corporations are barred from doing business with El Aissami, and all his assets within the country are frozen.

Amid rapidly deteriorating relations between the US and Mexico, reports are emerging that President Donald Trump openly threatened military intervention in a phone call with his counterpart Enrique Peña Nieto. According to a partial transcript of the conversation obtained by the Associated Press, Trump told Peña Nieto: "You have a bunch of bad hombres down there. You aren't doing enough to stop them. I think your military is scared. Our military isn't, so I just might send them down to take care of it." ("Bad hombres" is a term Trump also used in his final debate during the presidential campaign to refer to Mexican narco-gangs.)

A group of mothers in the Mexican state of Veracruz who came together to search for missing loved ones announced Aug. 14 that they had disovered a total of 28 clandestine graves with remains of some 40 bodies. The women banded together under the name Colectivo Solecito to search for their kin after growing tired of waiting for authorities to do so. They said they found the graves since Aug. 1 in an area north of the port of Veracruz. The group's Lucia de los Angeles Diaz Genaocalled the area "a great cemetery of crime" that is used "like a camp to kill people who have been kidnapped." The discovered remains have been exhumed and delivered to police for forensic analysis.

The Zapatista rebels in Mexico's southern state of Chiapas marked the anniversary of their 1994 New Years Day uprising by hosting a national activist gathering in their territory. Guests of honor at the proceedings in the small pueblo of Oventic were a group of parents and other family members of the 43 students who disappeared in September 2014. The students, from Ayotzinapa in Guerrero state, are said to have been abducted by corrupt local police and turned over to a murderous narco-gang—but surviving kin and their supporters increasingly charge Mexico's government with a cover-up in the case. The Zapatistas' Subcommander Moises, joined by 43 masked rebels (one for each missing student), oversaw the ceremony and each embraced the family members. Moises expressed his own skepticism of the official investigation: "The Zapatistas believe that we cannot trust the bad governments anymore, they are the servants of capital, stewards of big capitalist business," he said. "The one calling the shots is global capitalism, that is why we cannot believe them." (TeleSur, Jan. 1)

Mexico on Sept. 30 extradited 13 people to the United States—including two accused drug lords and several suspects in two high-profile attacks on US citizens. One was the 2011 deadly ambush of US immigration agents in San Luis Potosí state; the other the previous year's killing of US consulate workers in Ciudad Juárez. The two accused kingpins were Edgar Valdez Villarreal AKA "La Barbie" of the Beltran- Leyva Organization and Jorge Costilla Sánchez AKA "El Coss" of Los Zetas. The US Justice Department hyped the extraditions as signaling a new binational coordination following a June meeting between US Attorney General Loretta Lynch and her Mexican counterpart, Arely Gómez. As AP noted, extraditions had fallen dramatically since 2012, the final year of President Felipe Calderón's term, when Mexico sent 115 people to face criminal charges in the US. Under President Enrique Peña Nieto, the number dropped to just 66 last year. (AP, Sept. 30)

After an electoral season marred by narco-violence and assassination of candidates of all parties, the results from Mexico's June 7 vote are in. The coalition led by the Institutional Revolutionary Party (PRI), which ruled Mexico as a one-party state for 80 years, maintains its slim majority in the lower-house Chamber of Deputies, although it lost some seats. Gubernatorial races were also held in several states, including some hit especially hard by the cartel violence. The PRI gained the governorship of Guerrero, but lost control of Michoacán to the left opposition. In one upset, the PRI lost northern Nuevo León state to an independent, Jaime "El Bronco" Rodríguez Calderón—the first independent candidate to win a governorship in Mexico. The gadfly rancher survived two assassination attempts by the Zetas when he was mayor of García, a Monterrey suburb. His son was killed in an attempted abduction, and his young daughter kidnapped, although returned unharmed. El Bronco beat the PRI and other estabished parties with a populist campaign and invective against entrenched corruption. With the state's establishment press bitterly opposed to him, he made deft use of social media to mobilize support. (Reuters, BBC News, Televisa, CNN México, June 8)

Mexican authorities on March 4 announced the capture of Omar Treviño AKA "Z-42"—leader of Los Zetas, the ultra-violent narco-paramilitary network that has long terrorized the country. Z-42 was detained without a shot being fired by federal police and soldiers in San Pedro Garza García, an upscale suburb of northern industrial hub Monterrey, officials said. US DEA chief Michele Leonhart congratulated Mexico, saying the bust "strikes at the heart of the leadership structure of the Zetas." The US State Department had a $5 million price on Treviño's head, while Mexican authorities offered $2 million.

Police agents in San Fernando in the northeastern Mexican state of Tamaulipas aided Los Zetas drug gang in carrying out massacres of hundreds of Central American migrants and others in 2010 and 2011, according to a partially redacted document declassified by Mexico's Attorney General's Office (PGR). Although collusion between local Tamaulipas police and criminal gangs was already well known—US diplomatic cables released by the US government in 2013 discussed it, and locals refer to the police as "polizetas"—this is first time that the PGR has been required to release a document from an ongoing criminal investigation. Previously federal prosecutors had insisted that Mexican freedom of information laws didn't apply to open investigations. The document is now available on the website of the Washington DC-based National Security Archive, along with other relevant documents, including reports from US government agencies and US diplomatic cables released by the WikiLeaks group.
