According to a report by The New York Times, private-equity giant Blackstone group is struggling to secure funding for the massive, Saudi-backed infrastructure fund that the firm revealed last May. Business Insider reports that Blackstone unveiled the 40 billion-dollar fund for US infrastructure projects amid President Donald Trump's visit to Saudi Arabia last year. The Saudi Public Investment Fund reportedly pledged 20 billion-dollars, while Blackstone was supposed to cover an equal amount.
