US president Barack Obama invoked executive privilege on June 20 to justify the Justice Department's refusal to provide the House of Representatives with some of its documents relating to Operation Fast and Furious, a bungled program in which the Bureau of Alcohol, Tobacco and Firearms (ATF) inadvertently let about 2,000 firearms "walk" into Mexico during 2009 and 2010. Rep. Darrell Issa (R-CA), the chair of the House Oversight and Government Reform Committee, had subpoenaed the documents from the Justice Department. The House of Representatives could vote to hold Attorney General Eric Holder in contempt for refusing to comply with the subpoena.

The Inter-American Commission on Human Rights (IACHR, or CIDH in Spanish), an agency of the Organization of American States (OAS), reported on June 18 that eight members of the LGBT community in the southern Mexican state of Guerrero have been murdered since the beginning of the year. The latest victim was 18-year-old Antonio Calderón Peralta, whose body was found in Chilpancingo, the state capital, on June 9. The youth, who was dressed in women's clothes, had been beaten to death. The discovery of Calderón's body came two days after Guerrero's LGBT community held a march in Chilpancingo supporting sexual diversity.

Honduran national Cintia Yadira Herrera died of heart problems on June 18 shortly after arriving at San Pedro Sula in northern Honduras on a mass deportation flight arranged by US immigration authorities. She took a few steps after disembarking from the plane in Ramón Villeda Morales Airport and then collapsed, according to firefighters who came to her assistance; she died in the airport. Herrera was 33 or 34, according to different media reports, and was the mother of three children.

The 1,500 workers in Costa Rica's two Caribbean ports, Limón and Moín, went on strike on June 12 to oppose a 30-year concession the government of President Laura Chinchilla has granted to a Netherlands-based container management multinational, APM Terminals. The two ports handle about 80% of the country's international trade.

Brazilian soldiers from the United Nations Stabilization Mission in Haiti (MINUSTAH) made three attempts on June 15 to enter the Human Sciences Faculty (FASCH) of the State University of Haiti (UEH) in Port-au-Prince by force, according to faculty, students and local media. "We don't know the reason for this criminal and inopportune visit," the FASCH's dean, Hancy Pierre, told the online Haitian news service AlterPresse. "It's a disgrace for the country." In Haiti security forces are expected to get permission from university authorities before entering a campus.

The cholera epidemic that has killed more than 7,200 people in Haiti since October 2010 could possibly be brought to an end "in just months," according to a leading French cholera expert, Dr. Renaud Piarroux. "But it would be necessary to go all out in the areas where cholera is being transmitted," he added in a little-noted interview with Radio France Internationale on Apr. 16, "and, of course, we'd need to have the means of identifying [the cholera], with an epidemiological surveillance that is faster and more effective than what is being done currently."

After more than a week of student anti-austerity demonstrations in Sudan, President Omar al-Bashir finally responded to the movement on June 24, telling a gathering of students affiliated to his ruling National Congress Party (NCP) in Khartoum that the protesters are "bubbles and aliens" who will be "dealt with." He urged students not to listen to the "conspirators, traitors and collaborators"—words usually used to describe armed rebels in Darfur and South Kordofan. He also implied the protesters are tools of the US: "We are not afraid of being overthrown by anybody. Not America or anyone else because it is Allah who gives the rule." In comments the next day, Finance Minister Ali Mahmoud said the government had no choice but to cut spending in response to a budget gap. "If international oil prices go up, we'll increase fuel prices," he told reporters in Khartoum. "We will not retreat from the decision to lift the subsidies."

The US Supreme Court on June 25 ruled 5-3 that three provisions of Arizona's controversial immigration law, SB 1070, are preempted by federal law but upheld the most controversial provision. In Arizona v. United States, four specific provisions of the law were at issue: Section 2(B), which requires police officers to check the immigration status of anyone whom they arrest and allows police to stop and arrest anyone whom they believe to be an illegal immigrant; Section 3, which makes it a crime for someone even to be in the state without valid immigration papers; Section 5(C), which makes it a crime to apply for or hold a job in Arizona without proper papers; and Section 6, which gives a police officer the power to arrest an individual, without a warrant, whom the officer believes has committed a crime that could cause him or her to be deported, no matter where the crime may have occurred. In his opinion, Justice Anthony Kennedy found that sections 3, 5(C) and 6 intruded in areas reserved for the federal government:
