Twenty-two youth are suing the Trump administration over the president’s executive orders aimed at supporting the fossil fuel industry, curbing renewable energy and suppressing climate science. “The uncontested purpose of these executive orders is to expand fossil fuel use and suppress its biggest competitors,” Olsen said. ‘Every tonne matters’“Have the Executive Orders caused climate change?” attorney Miranda Jensen asked plaintiffs’ expert witness Steven Running. It’s really pretty straight forward.”Attorneys for the youth also called John Podesta to testify as a witness focusing on a president’s power to utilize executive orders. Sawyer said challenging broad, sweeping executive orders ordering agencies to consider their regulatory actions was not the correct avenue.
