U.S. presidential candidate Hillary Clinton talked to steel workers in the Appalachian region about their economic struggles on Monday, as she tried to win over blue-collar voters in a part of the country where support for Republican Donald Trump is strong.

Turning her attention beyond the Democratic Party nomination fight to a possible match-up against Trump on Nov. 8, Clinton met union leaders and some of the 600 workers who were laid off last year when AK Steel Holding Corp. announced it would idle a furnace in eastern Kentucky.

She said job losses in manufacturing and the coal industry in the area had been a heavy blow.
