Juan Guaido, president of National Assembly, shows marks on his wrists which he says are from handcuffs, to supporters at a rally in Caraballeda, Venezuela, Sunday, Jan. 13, 2019, as his wife Fabiana Rosales stands next to him. The new head of Venezuela’s increasingly defiant congress was pulled from his vehicle and briefly detained by police Sunday, a day after the U.S. backed him assuming the presidency as a way out of the country’s deepening crisis.
