On January 12, 2010, as acting governor, McClintock was placed in charge of Puerto Rico's Haitian relief efforts by Governor Fortuño, which included a $4.5 million Telethon benefitting the Red Cross and collecting millions of pounds of aid, reportedly the largest shipment of non-governmental aid sent during the first two weeks of the relief effort. On January 20, McClintock made a 4-hour visit to Port-au-Prince, Haiti, where, along with Puerto Rico journalist Carmen Jovet, he met with President Préval and Prime Minister Bellerive to coordinate Puerto Rico's relief efforts. He subsequently met with Preval in San Juan and was appointed by Secretary Hillary Clinton as part of the United States delegation to a meeting in Martinique in March 2010 to plan the multi-nation redevelopment of Haiti. He also helped coordinate Puerto Rico's initial response to the massive February 27, 2010, earthquake in Chile.
