On Monday, the Supreme Court heard arguments in the key First Amendment case Americans for Prosperity v. Rodriguez, which centers on the State of California’s requirement that nonprofit organizations disclose their donor information to the state. Back in 2015, then-Attorney General Kamala Harris (D-Calif.) demanded that two conservative nonprofits, 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. Legal representatives for AFP and TMLC said the Supreme Court justices’ questions and remarks suggested they are likely to strike down California’s requirement as an unconstitutional violation of the First Amendment.
