Protesters gathered in parts of Maryland on Thursday to commemorate the life of civil rights activist John Lewis and to protest actions and policies from the Trump administration.

The “Good Trouble Lives On” national day of action honors the late congressman and civil rights leader John Lewis. Protests are expected to be held along streets, at court houses and other public spaces. Organizers are calling for them to be peaceful.

Protests are planned across the nation on Thursday, the anniversary of civil rights icon and Congressman John Lewis’ death. Lewis famously coined the term “good trouble” to describe nonviolent civil disobedience that challenges unjust systems.
