The head of the National Association for the Advancement of Colored People on Saturday urged readers to boycott the New York Post, calling a cartoon that the newspaper published an invitation to assassinate President Barack Obama.
Benjamin Todd Jealous, the civil rights group's president, called on the tabloid to remove editor-in-chief Col Allan, as well as longtime cartoonist Sean Delonas.
Earlier this week, the newspaper apologized to anyone who might have been offended by the image printed Wednesday, which some say likens the nation's first black president to a violent chimpanzee gunned down by police in Connecticut.
Jealous said the cartoon was "an invitation to assassination."
On Thursday, after protests by notable figures including director Spike Lee, the paper posted ansaying the cartoon was meant to mock the federal economic stimulus bill, but "to those who were offended by the image, we apologize."
A spokeswoman for the newspaper referred The Associated Press to the paper's editorial when asked Saturday about the proposed NAACP boycott.
Critics said the cartoon recalled historical racial stereotypes of African-Americans depicted as monkeys.
Jealous called the editorial "a half of an apology, without elaboration."
The drawing, he said, "picks off the scabs of all the racial wounds."
He spoke as the NAACP gathered for its annual meeting in New York, where it was founded a century ago.
NAACP officials said that if the Post does not take "serious disciplinary action," they would reach out to organizations across the country to join them in their efforts against the tabloid.
NAACP Chairman Julian Bond called the publication of the cartoon "thoughtlessness taken to the extreme... Anyone who is not offended by it does not have any sensitivity."
