Organizers say taxpayers aren't footing the bill for Kanye West's headlining performance at the Pan Am Games closing ceremony on Sunday.
They also aren't sure whether the rapper's mic problems and abrupt exit from the stage were genuine or planned.
Pan Am Games CEO Saad Rafi says performance fees for West and the two other performers Canadian howler Serena Ryder and Miami pop-rapper Pitbull were covered by the concert promotion company Live Nation, which sponsored the Games.
He says the Games organizing committee only contributed to expenses such as backing bands, makeup artists and transporting artists' equipment from the airport.
There was a fleeting outcry when West was announced as the headliner for the ceremony, with several thousand people signing a petition urging organizers to replace him with a Canadian act.
Some questioned whether tax dollars should be spent on an American and often controversial artist.
