From Bread #12506: Terrorist sits on Board of BLM Fundraiser
"….charity’s website until Wednesday when the page was taken down…..
Susan Rosenberg was identified as the vice chair of the Thousand Currents board of directors on the charity’s website until Wednesday when the page was taken down after the conservative think tank Capital Research Center detailed her involvement with a communist terrorist group that had carried out bombings in New York and Washington, D.C., in the early 1980s."
With "Charity" being the operative word, found Thousand Currents 2017 IRS Form-990 here: https://apps.irs.gov/app/eos/
Susan Rosenberg is indeed the vice chair. TC's board looks interesting (cap related - doc. page 7 of 70) The other interesting thing about this group is that they made grants in excess of a million dollars to foreign entitites in 2016. It's almost as if they were/are funding caravans or something although there's no proof in this document.
