CLEVELAND (AP)–Boos filled the convention hall in Cleveland as one-time presidential candidate Ted Cruz finished his prime-time speech to Republican activists.

The jeers rained down after the Texas senator refused to endorse Trump – now the official GOP presidential nominee – in his address.

Cruz finished second to Trump in the delegate count and the two were bitter rivals during the primary campaign.

Cruz told supporters to vote their conscience – and not to stay home for the general election in November.

The boos stopped once Trump entered the convention hall.
