There are two older ResistBot petitions, one for Protection of Cultural Heritage and one for Peacebuilding and Diplomacy. I made one to Biden and Congress calling for an end to conflicts and abuses and for aid to be sent to DRC.
Go to FriendsOfTheCongo.org, where you can send a letter to tech & auto companies demanding them to do the right thing, join the Free Congo movement, and donate to Friends of the Congo. They also have an Action Network petition to Congress.
Stop Forced Evictions in the DRC from Amnesty USA. There’s a petition to DRC President Tshisekedi, a phone script for the Congolese embassy, and an email script to Secretary Blinken.
