Kerry: US may not recognize new Venezuelan president

In any event, Kerry said, the administration is unlikely to send a delegation to Maduro's inauguration. President Obama sent Rep. Gregory Meeks (D-N.Y.) to Chavez's funeral last month to try to repair ties with the country. 

“I'd be very doubtful of that,” Kerry said. “There's certainly no plan to.”

Some 15 countries – including Bolivia, Ecuador, Nicaragua, Iran, China, Saudi Arabia, Qatar, Haiti, Uruguay and Argentina – have already announced they were sending high-level delegations to the swearing-in, according to the Maduro government.
