Billionaire philanthropist Laurene Powell Jobs has ended a planned partnership with former New Republic literary editor Leon Wieseltier after learning of "past inappropriate workplace conduct," her organization said in a statement Tuesday.

Wieseltier was to be the editor of a publication, tentatively titled Ideas, that would have been bankrolled by the Emerson Collective, a philanthropy and advocacy organization headed by Jobs, the wife of Steve Jobs, the late co-founder of Apple.

"Upon receiving information related to past inappropriate workplace conduct, Emerson Collective ended its business relationship with Leon Wieseltier, including a journal planned for publication under his editorial direction," the organization said in its statement. "The production and distribution of the journal has been suspended."

It offered no further comment.

Wieseltier, a Brookings Institution fellow, apologized "for my offenses against some of my colleagues in the past," according to a statement obtained by Politico. "I offer a shaken apology and ask for their forgiveness," he wrote. "The women with whom I worked are smart and good people. I am ashamed to know that I made any of them feel demeaned and disrespected. I assure them that I will not waste this reckoning.

"And I am profoundly sorry to my extraordinary collaborators at the journal we began together that the misdeeds of my past have made it impossible to go forward," he continued. "My gratitude to them is boundless."

The development appears to be another piece of fallout from revelations about Harvey Weinstein, the Hollywood mogul who allegedly harassed and assaulted actresses for decades.

Wieseltier's name appears on a list of men involved in the media industry who are suspected of harassing behavior. The list is unverified and its authors anonymous, but it has been passed virally in recent days since Weinstein's exposure in the New York Times and New Yorker magazine.

Jobs, who lives in Palo Alto, Calif., has two direct connections to the Washington area. In July, she acquired a majority stake in the Atlantic magazine. Earlier this month, she purchased a 20 percent stake in Monumental Sports, which owns the Washington Wizards basketball team, the Washington Capitals hockey team and Capital One Arenain downtown Washington. Monumental's largest shareholder is Ted Leonsis.

The Emerson Collective is a philanthropy that advocates for policies concerning education and immigration reform, social justice and environmental conservation.
