Marianne Williamson, a self-help author who twice ran for president, announced Thursday that she is running for chair of the Democratic National Committee.

In an open letter to DNC members posted online, Williamson laid out her plan for the party as it seeks to move forward after losing the White House and Senate in November. She urged Democrats to sign a petition to allow her to participate in candidate forums that will be held in January.

DNC members will elect the party’s new chair and other officers at its winter meeting Feb. 1. There will also be a series of four forums to allow those running for DNC chair to speak with party members and lay out their vision for the Democratic Party.

“As chairwoman, I will work to reinvent the party from the inside out,” Williamson wrote in her pitch to DNC members. “For if we want a new president in four years, and a new Congress in two, then we must immediately get about the task of creating a new party.”
