On Friday, the U.S. Supreme Court took up two vitally important cases dealing with the freedom of speech and association. Back in 2015, Attorney General Kamala Harris (D-Calif.) demanded that two conservative nonprofit organizations, Americans for Prosperity (AFP) and the Thomas More Law Center (TMLC), hand over their donor lists. This demand threatened to reveal the identity of donors, potentially subjecting them to threats and harassment for supporting these groups. It also flew in the face of a 1958 Supreme Court decision upholding Americans’ right to support causes they believe in without government harassment.
