Then I guess you would have to look at Thousand Currents as they appear to be the 501(c)(3) that BLM is handled under. https://www.influencewatch.org/non-profit/thousand-currents/I'd like to look at more of their finances. My family has a charity ( 501c3 ) for a college scholarship (2) in memory of our son who died in 2008. Each year I file 990N stating we received under $50,000. in donations. If you receive more you have to include your expenses. I'd like to see their expenses.
