Former Vice President Dick Cheney has reportedly begun voicing criticisms of former President George W. Bush in private conversations with colleagues and associates. The Washington Post reports Cheney has expressed his frustration over his perception that Bush became more receptive to public opinion during their administration’s second term. A participant in one recent gathering said Cheney felt Bush had shunned his advice and had become “shackled by the public reaction.” Cheney has held the conversations as he works on his forthcoming memoir.
