As former Venezuelan President Nicolás Maduro and his wife face drug trafficking and other federal charges in the U.S., virtually all of the ousted leader's inner circle — including some with whom he's accused of running a cartel that allegedly smuggled tons of cocaine into the U.S. — remain in their posts.

A source briefed on the Trump administration's planning has told U.S. lawmakers that at least some members of that inner circle who, like Maduro, have been charged with crimes in the U.S., could be targets for further American military and law enforcement action.

Secretary of State Marco Rubio said on CBS' "Face the Nation with Margaret Brennan" that an operation to capture at least four of Venezuela's top officials in separate locations was deemed too complicated ahead of the U.S. strikes on the country, leading to the operation focused solely on Maduro as the top target, along with his wife.

Below is a look at some of the senior members of the Maduro regime who remain in Caracas, in some cases with U.S. bounties on their heads.

Delcy Rodríguez

The most senior member of Maduro's inner circle untouched by the U.S. attacks and raid over the weekend is the country's former Vice President Delcy Rodríguez, who was sworn in soon after the American raid as the new interim president, taking the reins from her longtime political mentor.

The 56-year-old has long been seen as a loyal confidant and protege of the now-deposed Venezuelan leader, and a member of a cadre accused by Washington for many years of helping Maduro maintain his authoritarian grip on power.

It remains unclear if Rodríguez and the Trump administration might find a way to work together, and thus whether she might remain in power to some degree following Mr. Trump's assertion that the United States will "run" Venezuela for some unspecified period.

Mr. Trump warned after Maduro's capture that if Rodríguez "doesn't do what's right, she is going to pay a very big price, probably bigger than Maduro."

Diosdado Cabello

Another stalwart of the Maduro regime is Diosdado Cabello, who currently serves as Minister of Interior, Justice and Peace, giving him oversight of the country's police and prisons. 

Cabello previously served as vice president, and for many years as president of the country's parliament. He also spent years in command of Venezuelan intelligence services. 

Like Maduro, he has been indicted on criminal charges in the United States, accused of helping to traffic more than 5 tons of cocaine to the U.S.

He was first charged in 2020 with various federal drugs and weapons offenses in an indictment filed in the same Southern District of New York where Maduro was arraigned. The indictment named Cabello as a senior figure in the Cartel del los Soles, which Maduro is accused of leading.

He was hit with further charges in a superceding indictment filed as the U.S. launched the attack on Venezuela. He's been described as the "chief thug" in terms of running Venezuela's domestic security forces, who helped keep Maduro in power, and the indictment lays out his alleged ties to drug cartels. 

Cabello could be among the targets of further U.S. military and law enforcement action, the source told CBS News' Brennan on Wednesday.

There is a U.S. government reward of $25 million on offer for information leading to Cabello's capture. 

Vladimir Padrino López

Vladimir Padrino López, currently serving as Venezuela's Minister of Defense, is also accused of direct involvement in trafficking drugs into the U.S.

The U.S. accuses him of allowing the safe passage of commercial flights carrying illegal drugs, and of collecting a protection fee for doing so, and he was indicted in a federal court in Washington D.C. in 2020.

Padrino, who has longstanding ties with Russia, also has a U.S. bounty on his head, with a $15 million reward on offer. 

Jorge Rodríguez

The new interim president's brother, Jorge Rodríguez, has served as President of the National Assembly of Venezuela, the country's Maduro-controlled legislature, since 2021. He's also considered a key figure in the regime. 

"My main function in the days to come... as president of this National Assembly, will be to resort to all procedures, all platforms, and all avenues to bring back Nicolas Maduro Moros, my brother, my president," Jorge Rodriguez told lawmakers.

Just like his sister, Rodríguez has been sanctioned by the U.S. Treasury over his alleged role in undermining democracy in Venezuela and propping up Maduro's authoritarian regime.  

Nicolás "Nicolasito" Ernesto Maduro Guerra

One of Maduro's sons, along with his mother Cilia, who was arraigned with her husband in New York on Monday, was also charged in 2020 with drug offenses relating to the Cartel de los Soles.

Nicolás Ernesto Maduro Guerra, 35, known in the country as Nicolasito, or Little Nicolás, is currently the deputy president of the legislature. He is also sometimes referred to as "The Prince" in the country.

According to the U.S. indictment, the younger Maduro partnered with his father, other senior officials and "narcotics traffickers and narco-terrorist groups, who dispatched processed cocaine from Venezuela to the United States via transshipment points in the Caribbean and Central America."
