In media news, MSNBC has suspended the right-wing commentator Pat Buchanan following the publication of his book, “Suicide of a Superpower,” and his appearance on a white nationalist radio station. ColorOfChange.org and CREDO Action launched a petition drive last year to have Buchanan fired because of what one petition described as his “xenophobia, bigotry and hate speech.” In his new book, Buchanan writes that the “European and Christian core of our country is shrinking,” which is damaging the nation “ethnically, culturally, morally, politically.” One chapter of the book is titled “The End of White America.”
