Kamala Harris, the junior U.S. senator from California, is a woman in a hurry. Elected in 2016, Harris today announced her candidacy for president in 2020. “I’m running for president of the United States, and I’m very excited about it,” she told ABC’s “Good Morning America.” Her track record, however, suggests she would be the kind of president who among other things would cut ethical corners on behalf of labor unions. Back in 2015, Harris, as California attorney general, helped a powerful affiliate of the Service Employees International Union (SEIU) scotch the purchase of a half-dozen nonprofit health care facilities by a corporate buyer to protect union jobs. While a federal judge twice has dismissed allegations by the buyer, Prime Healthcare, that she abused her office, the case deserves another look.
