Francis Chung/E&E News President Biden faced Capitol Hill turmoil unlike anything in recent history during his first 100 days in the Oval Office with thin margins in both chambers and political upheaval confronting his ambitious energy and environmental agenda. Outgoing President Trump's supporters had stormed the Capitol in a democracy-defying riot just 14 days before Biden's inauguration. It led directly to a second impeachment trial for Trump, events that have only deepened political divides on the Hill.
