El circo (song)
The lyrics describe two brothers, "Carlos" and "Raúl" (in reference to Carlos Salinas de Gortari, president of Mexico from 1988 and 1994, and his brother Raúl Salinas de Gortari), who form a "circus" (a drug cartel) and get rid of the other "circuses" in the country. After the brothers get wealthy, Raúl makes Carlos' money disappear (a reference to the Mexican peso crisis) and their circus ends. Raúl is jailed, while Carlos leaves the country, and the people are finally at peace, unless another circus arrives and the story repeats itself.
Citigroup
In 1998, the General Accounting Office issued a report critical of Citibank's handling of funds received from Raul Salinas de Gortari, brother of Carlos Salinas, the former president of Mexico. The report, titled "Raul Salinas, Citibank and Alleged Money Laundering," indicated that Citibank facilitated the transfer of millions of dollars through complex financial transactions that hid the funds' paper trail. The report indicated that Citibank took on Salinas as a client without making a thorough inquiry as to how he made his fortune, an omission that a Citibank official called a violation of the bank's "know your customer" policy.
