for 35 years initially supported hillary clinton but i voted for trump. maybe a mistake. but i heard him say he ll bring coal back. reporter: a mistake maybe because yunts now suffers from black lung disease. from here throw. reporter: he voted for trump to bring jobs back now fears trump s promise to kill obamacare will also end his black lung benefits. if they re going to eliminate obamacare, they may eliminate all the black lung care. it may all be done. reporter: three sentences in the affordable care act made it easier for victims of black lung to get monthly benefits if they worked 15 years or more in the mines. and if they died, the benefits automatically extended to their widows. i will be drawing $643. and i think 42 cents. once a month?
