A Nevada newspaper owned by a Donald Trump mega-donor has savaged the US president's decision to pardon a Republican councilwoman who was convicted of using donations intended to fund a statue of a police officer to pay for cosmetic surgery. The Las Vegas Review-Journal, owned by the billionaire Miriam Adelson, described the decision as a "debasement of presidential pardon power" in a scathing editorial published after Trump granted clemency to Michele Fiore, a former Las Vegas councilwoman and Nevada state lawmaker. Fiore was convicted of fraud last year. Federal prosecutors said at trial that she had raised more than $70,000 for the statue of a Las Vegas police officer who was fatally shot in 2014 in the line of duty, but had instead spent it on cosmetic surgery, rent and her daughter's wedding.
