Tens of thousands of Guatemalans have taken to the streets since the May 10 slaying of a prominent lawyer who left behind a videotape saying that if anything happened to him it was at the behest of the country's president. "If you are watching this message, it is because I was assassinated by President Álvaro Colom with help from Gustavo Alejos," the president's private secretary, the lawyer, Rodrigo Rosenberg, said in the video. Rosenberg was shot while riding his bicycle near his home. In the tape, Rosenberg said officials might want to kill him because he represented a businessman who had refused to cooperate in a money-laundering operation sought by President Colom. The businessman, Khalil Musa, was killed with his daughter in April. Colom rejects the accusation, and has called for the FBI and UN-backed International Commission Against Impunity in Guatemala (CICIG) to investigate the case.

The Colombian Senate on May 19 approved a proposal to hold a referendum on amending the country's constitution to allow for a third presidential term.

The two proposals must be reconciled in a conference committee and be approved by the Constitutional Court before the referendum can take place.
