 His “wholesale” purchase of defaulted Argentinian bonds was considered an act of “loyalty” to Argentina by Kirchner and others.During Argentina's worst economic times, he bought into “almost all” of the country's large firms, “from Telecom to Transener.”

Martínez has been described as being “closely linked” to the late Argentinian president Nestor Kirchner and as having been a “friend” of Kirchner's.According to one source, “whenever the former president traveled to the United States, he made a place in his schedule” for a meeting with Martínez.
