U.S. President Donald Trump on Sunday threatened that Venezuela’s interim leader Delcy Rodriguez would pay a “very big price” if she fails to cooperate with Washington, after U.S. military captured and jailed her former boss Nicolas Maduro.

"If she doesn't do what's right, she is going to pay a very big price, probably bigger than Maduro," Trump told The Atlantic in a brief telephone interview.

U.S. forces attacked Caracas in the early hours of Saturday, bombing military targets and spiriting away Maduro and his wife to face federal narcotrafficking charges in New York.

The Trump administration says it is willing to work with the rest of Maduro's government as long as Washington's goals, including opening access to U.S. investment in the enormous Venezuelan crude oil reserves, are met.

Trump's warning came as Rodriguez was confirmed as interim president by Venezuela's Supreme Court and military officials.
