::::I think the sentence as it currently exists is fair and accurate: "In 1999, former radical activist Bill Ayers, who had hosted a fundraiser for Obama in 1996, joined the board;[13]; this association would later draw scrutiny during Obama's 2008 presidential campaign.[14]" The reference to Ayers is wikilinked, so anybody wanting to know more about him can research at their leisure and draw their own conclusions. An encylopedia should help people draw their own conclusions, not push them to have any particular opinion.
