Mexico defended the series of five stamps released Wednesday, which depicts a child character from a comic book started in the 1940s that is still published in Mexico.
But the Rev. Jesse Jackson said President Bush should pressure Mexico to withdraw the stamps from the market, saying they "insult people around the world."
"The impact of this is worse than what the president said," Jackson noted, referring to Fox's May 13 comment that Mexican migrants take jobs in the United States that "not even blacks" want. Fox later met with Jackson and expressed regret but insisted his comments had been misinterpreted.
While calling the stamps an internal issue for Mexico, White House spokesman Scott McClellan was quick to denounce the stamp images, reports CBS News Correspondent Mark Knoller. McClellan said "racial stereotypes are offensive no matter what their origin" and such caricatures have no place in today's world.
