According to the text, today's action seeks to warn Venezuela's military and intelligence services, as well as those who support them, that they will suffer serious consequences due to their continued support for the government of Nicolás Maduro, which Washington insists on qualifying as illegitimate.
Guaido declared himself interim president in January after calling Maduro's 2018 re-election a fraud.

In recent days, the government has sought to ramp up its own pressure on the opposition with the arrest of the No. 2 leader of the opposition-controlled National Assembly, Edgar Zambrano.
Venezuela's pro-government Constituent Assembly has stripped Guaido and eight other opposition legislators of their parliamentary immunity to prosecution following requests by the Supreme Court.
Trump's dissatisfaction lies with National Security Advisor John Bolton, who the president has said wants to get the U.S.
"We have said from the beginning that we will use all the resources at our disposal to build pressure".
