The Blackstone Group has asked outside fund managers to detail their ownership in companies that make or sell guns, the Wall Street Journal reported. Blackstone gave the managers about a day to answer, the story said. Blackstone sent the request by email to managers at about a dozen hedge funds that it owns a stake in, the WSJ said. The email asked for information about “any ownership or lending” of or to “gun manufacturers or gun sellers” the story said. The request represents the snowballing pressure on companies to cut ties with the firearms industry in the wake of the Parkland, Florida school shooting earlier this month, the WSJ said.
