Machado’s appearance at the rally was her first public appearance in months, since a government crackdown on Venezeulan opposition figures and their supporters last year.

María Corina Machado, the driving force of Venezuela’s opposition movement, was arrested by government security forces Thursday as she left a rally in Caracas, a day before President Nicolás Maduro plans to take office for a third term.

Venezuelan opposition leader Edmundo González, who claims to have defeated President Nicolás Maduro in last year’s presidential election, says that his son-in-law has been kidnapped in Venezuela’s capital.
