Demonstrators hold signs and a Venezuelan flag during a protest outside of the Goldman Sachs Group Inc. headquarters in New York, U.S., on Tuesday, May 30, 2017. Goldman faces a probe by Venezuela's opposition leaders after buying bonds issued in 2014 by the state oil company, a purchase some lawmakers said bolsters President Nicolas Maduro as he grapples with accusations of human-rights violations.
