Venezuela blocks Guaido from office as the opposition scoffs

Maduro dismisses Guaido's claim to the presidency as a Washington-backed effort to seize power in Venezuela, which is struggling under hyperinflation and crippling blackouts that have left millions of citizens without power this month.Venezuela's comptroller, Elvis Amoroso, said Guaido had failed to explain how he paid for foreign trips since joining the opposition-run legislature."The only body that can appoint a comptroller is the legitimate parliament," he said.
