WASHINGTON — President Barack Obama is hosting Mexican President Enrique Pena Nieto at the White House on Tuesday, looking to his southern neighbor for help in implementing the president's changing policies on immigration and Cuba. Obama wants Pena Nieto to join him in pressuring Cuba to make democratic reforms now that the White House is moving to re-establish diplomatic and commercial ties. The US-Cuba estrangement had been a point of friction with Latin American countries, including Mexico, that had normal ties with the communist island nation. Pena Nieto's government also could help spread the word of qualifications for Obama's plan to defer deportations for some 4 million immigrants in the US illegally. Two-thirds of those who are eligible are from Mexico. Both actions from Obama in recent weeks drew praise from Pena Nieto, who may be hoping his visit to the White House can help give him a boost after a 2014 marked by scandal, violence and corruption. That includes soldiers killing 22 civilians in a questionable “shootout” and revelations that Pena Nieto and his treasury secretary live in luxury homes built and financed by a favorite government contractor. Perhaps most notably, tens of thousands of protesters have taken to the streets to protest the Sept. 26 abduction and presumed murder of 43 college students, allegedly at the hands of local officials and police in league with a drug cartel. Pena Nieto told the country it was time to “move beyond” the case just weeks after their abduction, and he took a month to meet with the victims' families. Human Rights Watch wrote a letter to Obama Monday urging him to press Pena Nieto to take the case and “a broader pattern of abuse and impunity” in Mexico more seriously. Obama administration officials responded that the president plans to raise the issue of strengthening Mexico's law enforcement and judicial institutions during the visit, which includes an Oval Office meeting followed by a working lunch. Sergio Alcocer, Mexican undersecretary for North America affairs, said he didn't expect the students' abduction specifically to come up between the two presidents. Alcocer pointed out that the United States has had its own scandal and protests over the shooting of an unarmed black man, Michael Brown in Ferguson, Missouri. “We have cases of violence in different parts of the world,” Alcocer said. “Within the United States we know there has been this kind of violence in the area of Missouri, to mention just one case.” — AP
