MEGAN THOMPSON:

This 100th day of the Trump administration drew tens of thousands of demonstrators to the nation's capital — this time for what was called the People's Climate March.

The march began on Capitol Hill and made its way along Pennsylvania Avenue to the White House — demonstrators protesting Trump administration environmental policies.

Chief among them, dismantling president Obama's Clean Power Plan, which limited carbon dioxide emissions from burning coal to produce electricity.

The marchers also oppose President Trump's desire to withdraw from the 2015 Paris climate change accord, which committed the U.S. and 194 other nations to reduce emissions that cause global warming by 25 percent by the year 2025.
