MSLF attorney Tyler Martinez writes in Newsweek:

Back when Kamala Harris was attorney general of California, she did her best to invade the privacy rights of donors to nonprofit organizations. It did not matter that those very same privacy rights had protected members and supporters of the NAACP and other nonprofit groups in the 1950s, ’60s and ’70s.
Fortunately, a stunning cross-section of advocacy groups—from the ACLU on the Left to my firm, Mountain States Legal Foundation, on the Right—teamed up to fight back against Harris’ unconstitutional conduct. Conservative, liberal, progressive or libertarian—all saw the danger in California’s demand.
