Luke Popovich, a spokesman for the National Mining Association, told the Post that Obama administration officials, such as former Environmental Protection Agency Administrator Lisa Jackson and former Energy Secretary Steven Chu, have made appearances at the group's meetings in the past.

The meeting comes amid efforts by the Trump administration to roll back dozens of regulations. The real estate mogul-turned-president vowed on the campaign trail to lift restrictions on mining.
