text: Anti-Hillary Clinton street art emerged in Brooklyn just hours before Clinton's presidential candidacy announcement on Sunday. The signs feature portraits of Clinton with phrases including 'Dont Say Secretive', 'Don't Say Entitled' and 'Don't Say Ambitious'. The street art appears to be a dig at a group of Clinton supporters who said it would be on the look out for evidence of sexism in reporting about the Democratic politician, according to the Weekly Standard. Last month, the New York Times' Amy Chozick brought attention to the efforts made by the group, which goes by the name of 'HRC Super Volunteers'. The descriptive terms that Clinton's fan club said it does not want applied to their candidate include 'polarizing, calculating, disingenuous, insincere, ambitious, inevitable, entitled' and 'over confident.'
