Gov. Susana Martinez, who has touted herself as a champion of transparency, on Thursday vetoed legislation that would have required lobbyists to return to disclosing more information publicly about money they spend on public officials. The Legislature passed a law that weakened those rules last year but sought to correct what some lawmakers called an inadvertent mistake during this year’s 60-day session, which ended last month. Martinez’s veto means lobbyists won’t need to report expenses on lawmakers and other public officials under $100, as they did prior to the current law taking effect. Martinez explained her reasoning in a one-page veto message. “Various interpretations and ambiguity of the bill became clear” after discussion with the bill sponsor, Martinez wrote in her veto message, although she didn’t detail that ambiguity.
