Is George Soros a racketeer? The billionaire currency speculator, who in 1992 netted $1 billion by shorting the British pound and bringing the Bank of England to its knees, controls a large network of leftwing activist organizations from under the umbrella of his Open Society Foundations.  Days ago, President Donald Trump threatened Soros and his son, Alex, with prosecution under the Racketeer Influenced and Corrupt Organizations (RICO) Act, a 1970 law providing for extended criminal penalties against participants in ongoing criminal organizations. The law was meant to be a weapon for prosecutors against the Mafia, but it has been used in other contexts as well. Peter Schweizer and Eric Eggers discuss.
