Rockland’s county executive has vetoed the proposed “Rockland’s Future” summit passed by the legislature along party lines last month, with Democrats voting for it. In his veto statement, Rockland County Executive Ed Day said Rockland’s Human Rights Commission should be left to handle those types of activities. The summit would have included meetings that bring community leaders and residents together to focus on controversial issues, such as over-development, anti-Semitism and other expressions of hate, poverty, and cultural diversity.
