I’m blowing out my voice to get this sucker done,” Trump told the crowd after his mic stopped working mid-rally.

The former president promised energy independence and better microphones in event with technical difficulties.

The rally went on for another hour, but Trump, at times, struggled to move on from the initial audio failures; 20 minutes into the event, he was still complaining that he had to “scream” to get his message across, even as the audio system had been fully restored.
