What Does The Law Say About Trump's Campaign Meeting With Russian Lawyer

There have been several articles in the press about the meeting between Donald Trump Jr., Jared Kushner,  and Paul Manafort who was the Trump campaign manager at the time of the meeting.  Donald Trump Jr. stated that he asked Kushner and Manafort to attend the meeting because they might receive useful information from the person invited to the meeting at Trump Tower.  This article by a distinguished law professor explains how the meeting may be construed as collusion with a foreign government.  It will also become another avenue to pursue in the investigations that are underway.
