July 8 (Reuters) - The White House has defended its handling of Iran's visa restrictions during the World Cup, with top official Andrew Giuliani saying the team's decision to base themselves in Tijuana, Mexico, instead of Tucson was mutually beneficial. Giuliani, Executive Director of the White House Task Force for the World Cup, said the cross-border logistics worked smoothly for all parties despite Iran's complaints during the group stage and after they were knocked out of the tournament.
