President-elect Donald Trump says Venezuela's embattled opposition leader must be protected as President Nicolas Maduro takes the oath of office for a third six-year term.

Machado was released after a brief detention while leaving a protest in Caracas Thursday on the eve of President Nicolas Maduro’s inauguration.

During her detention, an aide said, Maria Corina Machado “was forced to record several videos.” She has garnered enormous support for her opposition to Nicolás Maduro.
