(CNN) – This time, White House Chief of Staff Rahm Emanuel has gone too far, Sarah Palin says.
The former Alaska governor is calling on President Obama to fire his notoriously coarse top aide after a report in the Wall Street Journal last week quoted Emanuel as referring to liberal groups in August who attacked the president's health care plan as "F-ing retarded."
In a posting on Facebook, Palin says the language is not only "caustic [and] crude" but deeply offensive to those with disabilities. She also compares the choice of words to that of the "N-word" in reference to African-Americans.
"His recent tirade against participants in a strategy session was such a strong slap in many American faces that our president is doing himself a disservice by seeming to condone Rahm's recent sick and offensive tactic," Palin wrote.
"Just as we'd be appalled if any public figure of Rahm's stature ever used the "N-word" or other such inappropriate language, Rahm's slur on all God's children with cognitive and developmental disabilities – and the people who love them – is unacceptable, and it's heartbreaking," Palin also wrote in the post Monday evening.
Palin's youngest child, Trig, was born with Down Syndrome in April, 2008.
Special Olympics Chairman Tim Shriver has also taken issue with the language, sending a letter to Emanuel last week asking him to join his organization's campaign to end the use of the word.
The White House has not commented on Emanuel's reported language.
