‘Trump Troubadour’ let down by former hero Kraig Moss became known as the ‘Trump Troubadour’ when he gave his time and money to support Donald Trump with his music during the US primaries. He was passionate because Trump promised to fight the scourge of heroin addiction, which took Moss’ son Rob three years ago. Now, Moss says he feels let down by Trump over his failed health care reform which didn’t act on Trump's campaign pledges to stop heroin addiction, and he worries this could signal how the president will approach other key policies.
