More than twenty thousand people have committed to protest Hillary Clinton’s likely nomination at the Democratic National Convention in Philadelphia. They’re calling the protest “Occupy DNC Convention,” and their number of pledged participants is quickly growing.

Their leaders have set up a Facebook group to organize transportation, accommodations and a PayPal donation link. The group also provides “study guide” documents on how to protest the convention, with documents titled “Civil Disobedience Training” and “Health and Safety at Militant Actions.” The documents give insight into first aid training and how to withstand teargas.

The protesters are united in their support for underdog Bernie Sanders, as well as their opposition to “a fraudulent Hillary nomination.” One document further adds they are “contesting Hillary’s nomination on the grounds of fraud, voter suppression, and corruption. We show them who we want.”

The group assures the protest will be nonviolent, and they already have received permits to protest and hold public demonstrations throughout Philadelphia.

“The Democratic Party has consistently betrayed their promises to the Black community and the 2016 presidential election is not going to be any different. We must capitalize off of this moment with one goal in mind; and that is to resist the capitalist and racist power structures that allow white supremacy and capitalist oppression to flourish. At the DNC, [we] plan to introduce our own Declaration of Independence and the People’s Constitution, one that liberates us from the corruption of American politics,” said the activists’ website.
