Venezuela’s vice president shrugged off U.S. sanctions identifying him as a major international drug trafficker, saying Tuesday that the actions by the Trump administration only deepen his commitment to the anti-imperialist revolution started by the late Hugo Chavez.

In a series of defiant messages posted on social media, Tareck El Aissami said the “miserable and defamatory aggression” by the U.S. won’t distract him from his job of rescuing Venezuela’s crashing economy from what he called sabotage by its conservative opponents.
