Interior Secretary Ryan Zinke confronted and chided protesters who interrupted him Wednesday as he delivered a speech on the Trump administration’s commitment to cleaner fuels as part of its “energy dominance” agenda.

Two protesters stopped Zinke’s speech at the National Press Club in Washington, D.C. recognizing National Clean Energy Week. One referenced Zinke’s ties to the fossil fuel industry. Another, off topic, complained about Trump’s Supreme Court nominee Brett Kavanaugh.
