State Department warns US citizens to leave Venezuela

Delcy Rodriguez has been formally sworn in as the interim president of Venezuela, the country's foreign ministry confirmed to ABC News. Rodriguez served as Nicolas Maduro's vice president.

Rodriguez, who was sworn in at the country’s parliament building, made a short statement that did not mention Maduro.

"I swear on my honor that I will not rest my arm nor give peace to my soul until I see Venezuela reach its rightful destiny, on the pedestal of honor it deserves as a free and sovereign nation," she said in Spanish. "I swear to the people of Venezuela that I will not rest for a single minute until I guarantee the peace of the Republic, the spiritual tranquility of our people, and the economic and social stability of our country."

The U.S. is considering reopening its embassy in Venezuela, according to a senior State Department official.

“As President Trump said, we are making preparations to allow for a reopening should the president make that decision," the official said.

The embassy has been closed since March 2019, when the State Department withdrew all diplomatic personnel in Caracas.

Nicolas Maduro’s son gave an impassioned speech tp Venezuelan lawmakers on Monday.

"If we normalize the kidnapping of a head of state, no country is safe," Nicolas Maduro Guerra said in Spanish.

Maduro Guerra, who is a member of Venezuela's National Assembly, said Venezuela isn't fighting for its land or its rights, but for its well-being and the well-being of the entire human existence.

In a message to Maduro, he said, "Your country is in good hands, father, and soon we'll hug in Venezuela."

Maduro Guerra was met with applause and multiple standing ovations during his almost 30-minute speech.

He is among those charged in a superseding indictment unsealed on Saturday that accused his father of allowing "cocaine-fueled corruption to flourish for his own benefit, the benefit of members of his ruling regime, and for the benefit of his family members."

During their arraignment in Manhattan federal court, Nicolas Maduro and his wife both pleaded not guilty.

“I am innocent. I am not guilty. I am a decent man. I am still president of my country," Maduro said through an interpreter when the judge asked for his plea.

His wife, Cilia Flores, responded similarly, saying, "Not guilty. Completely innocent."

While confirming his identity at the start of the hearing, Maduro declared through an interpreter, "I am the president of Venezuela."

"I was captured at my home in Caracas, Venezuela," he added, before the judge interrupted and told him there would be time later to challenge his custody.

Neither Maduro nor Flores are seeking bail. The judge said he is open to receiving a bail application in the future but the couple will otherwise remain detained at MDC-Brooklyn.

Flores' attorney said she "sustained significant injuries" during the military operation and requested a medical briefing.

"There’s worry she may have a fracture or severe bruising on her ribs," her attorney, Mark Donnelly, said.

They are next due in court on March 17.
