“Paul Manafort, President Donald Trump’s disgraced former campaign-manager, pleaded guilty to on September 14th. Many have focused on what Mr Manafort, who was convicted on eight counts of financial crimes in a separate trial in August, might tell Robert Mueller, the special counsel investigating the Trump campaign’s possible collusion with Russia. Of that, much is speculated, but little is known. Yet the nature of Mr. Manafort’s crimes has also shed light on unregistered foreign lobbying, the murkiest part of a swampy industry.” Those are the opening lines of Idrees Kahloon’s Economist article “Crimea river: The swampy business of lobbying for foreign governments.” In this installment of “Leonard Lopate at Large,” Idrees and Ben Freeman of the Center for International Policy will talk about this disturbing area of foreign policy.
