President Donald Trump said Saturday that Venezuela’s opposition leader lacks the support and legitimacy needed to govern the country following the removal of President Nicolás Maduro.

Trump’s remarks came hours after the United States led military operations in Venezuela that resulted in the capture of Maduro and his wife, Cilia Flores, who were taken into U.S. custody to face long-standing narco-terrorism charges.

Venezuelan opposition leader and Nobel Peace Prize laureate María Corina Machado praised the operation in a statement, describing it as a turning point for the country.

“As of today, Nicolás Maduro faces international justice for the atrocious crimes committed against the Venezuelan people and citizens of many other nations,” Machado said. “In light of his refusal to accept a negotiated solution, the government of the United States has fulfilled its promise to uphold the rule of law.”

Despite her support for the operation, Trump said he has not spoken with Machado and expressed skepticism about her ability to lead Venezuela during a transition period.

“I think it would be very tough for her to be the leader,” Trump said during a press conference. “She doesn’t have the support within or the respect within the country. She’s a very nice woman, but she doesn’t have the respect.”

Trump also announced that the United States would temporarily oversee Venezuela’s governance as the country transitions to new leadership.

“We’re going to run the country until such time as we can do a safe, proper, and judicious transition,” Trump said. “It has to be judicious. We want peace, liberty, and justice for the great people of Venezuela.”

U.S. officials have not provided further details on how such an interim arrangement would function or how long it would last.
