Venezuela’s government has announced another investigation against opposition leader Maria Corina Machado, continuing its efforts to blame her for the economic sanctions that the United States has imposed against the South American country.

Venezuelan authorities are investigating opposition leader Maria Corina Machado for alleged treason after she expressed support for a US bipartisan bill that seeks to block Washington from doing business with any entity that has commercial ties with the government of Venezuela’s President Nicolas Maduro.

U.S. Secretary of State Antony Blinken on Tuesday called Venezuela's Edmundo Gonzalez the country's "president-elect" for the first time, signaling that Washington wants to step up pressure on President Nicolas Maduro.
