According to media reports, the Venezuelan Supreme Court also blocked all of the self-proclaimed interim president's bank accounts and financial transactions within the country's jurisdiction on Tuesday.
Venezuelan authorities have launched a preliminary investigation into the activities of the country's opposition leader Juan Guaido, Reuters reported Tuesday, citing a statement by the Venezuelan Supreme Court's president. In particular, the court's ruling imposes a travel ban on Guaido until the completion of the investigation.
Earlier this week, Venezuelan Prosecutor General Tarek Saab asked the Supreme Tribunal of Justice to introduce these preventive measures against Guaido, who is the head of the National Assembly. US National Security Adviser John Bolton said Tuesday that the United States condemns Venezuelan prosecutors for threatening Guaido, and he warned of "serious consequences for those who attempt to subvert democracy and harm Guaido".
Meanwhile, the US Department of State has granted Guaido the authority to take control of certain Venezuelan government assets. State Department spokesperson Robert Palladino emphasized on Tuesday that the certification would allow Venezuela's opposition leader to "safeguard" government assets for the benefit of the people of Venezuela.
Bolton announced Monday that the Trump administration was imposing sanctions against Venezuelan state-run oil giant PDVSA, adding that it will block $7 billion in PDVSA's assets. US Treasury Secretary Steven Mnuchin told reporters that by blocking PDVSA assets, the United States is taking care of the company in the interests of the people of Venezuela and also taking measures to protect its own market.
