From the introduction to the letter:
The undersigned civil rights, student, community, and consumer advocacy organizations, along with faith leaders from across the country, urge you to use the authority of executive action to cancel $50,000 of federal student loan debt per borrower to stimulate the economy, bridge the racial wealth gap, and alleviate the financial suffering of millions of Americans, including Black women. While women carry around two-thirds of student debt, Black women are more than twice as likely as white men to owe more than $50,000 in undergraduate student loan debt.
