Quote:At the time, top Justice officials suspected Flynn of violating the Logan Act, the 218-year-old law under which no one has ever been prosecuted, that prohibits private citizens from acting on behalf of the United States in disputes with foreign governments. Starting in the summer of 2016 and intensifying in the transition period, the Logan Act, while mostly unknown to the general public, became a hot topic of conversation among some Democrats. A number of lawmakers, former officials, and commentators called on the Obama administration to investigate the Trump team for a possible Logan Act violations — and to do it while Democrats still controlled the executive branch.

At the same time, inside the Obama Justice Department, it appears the Logan Act became a paramount concern among some key officials in the critical weeks of December 2016 and January 2017. Former Deputy Attorney General Sally Yates has told Congress that the Logan Act was the first reason she intervened in the Flynn case — the reason FBI agents were sent to the White House to interview Flynn in the Trump administration's early days. It was that interview, held on Jan. 24, 2017, that ultimately led to Flynn's guilty plea.
