Trump said that Venezuela’s new leader, Delcy Rodríguez, would help the United States run Venezuela. She quickly said the opposite.

Trump said Delcy Rodríguez was sworn in as Venezuela’s interim president and would act as a partner in letting the United States run the country.

Less than two hours later, Ms. Rodríguez — who was Nicolás Maduro’s vice president — delivered a televised address to Venezuela that made clear she viewed the United States as an illegal invader that must be rejected.
