Yellow vest protestors hoist an effigy with a French national flag in front of The Arc de Triomphe on The Champs-Elysees in Paris on January 5, 2019, during a rally by yellow vest "Gilets Jaunes" anti-government protestors. Over the past six weeks, "yellow vest" demonstrators -- so-called after the high-visibility jackets they wear -- have repeatedly clashed with police in Paris and other big cities, plunging Macron's presidency into crisis. The "yellow vest" movement began in rural France over fuel taxes and quickly ballooned into a wider revolt against the 41-year-old president's pro-business policies and perceived arrogance by low-paid workers and pensioners.
