It is not viable for Venezuelan opposition leader Edmundo Gonzalez to enter the country, his ally Maria Corina Machado said on Friday, shortly after President Nicolas Maduro was sworn in for a third term despite months of controversy over the country's contested July election.

Today, Maduro officially violated the constitution,” María Corina Machado, the popular opposition leader who was briefly detained yesterday, said in a video posted on social media in the afternoon. She called on Venezuelans to take to the street to protest.
