FILE - This Thursday, April 27, 2017 file photo shows George Soros, Founder and Chairman of the Open Society Foundation, before the start of a meeting at EU headquarters in Brussels. Soros contributed at least $1.5 million to support Diana Becton, who was appointed Contra Costa County's first woman and first African-American district attorney last year, and challengers seeking to oust sitting prosecutors in Alameda, Sacramento and San Diego counties. Becton may face a runoff election. (Olivier Hoslet/Pool Photo via AP, File)
