Republican presidential candidate Donald Trump will speak Thursday at the annual Shale Insight conference at Pittsburgh's David L. Lawrence Convention Center, organizers said Monday.
Conference officials told the Pittsburgh Tribune-Review that Democratic candidate Hillary Clinton was also invited but declined, citing a scheduling conflict.
The pro-drilling Marcellus Shale Coalition is co-sponsoring the event with the Ohio Oil and Gas Association and the West Virginia Oil and Natural Gas Association.
Trump's appearance comes after he spelled out an economic plan in which he claims he'll promote coal production, safe fracking and energy exploration in "appropriate" parts of federal lands. But Trump's proposal didn't spell out what government restrictions he wants to lift or modify to make that occur.
