Trace Cyrus has penned an emotional open letter to his father Billy Ray Cyrus on Instagram, writing that his dad isn't 'healthy' and his family is 'worried' about him. Trace's post came after his dad received criticism for his performance at President Donald Trump's inaugural festivities on Jan.

Billy Ray was one of the performers at Trump’s Liberty Ball. Social media users deemed the show a “disaster” as the country artist reacted bizarrely after experiencing technical difficulties. Afterward, he took to Instagram to give some insight into what went wrong.
