A US judge on Friday tentatively rejected Republican presidential nominee Donald Trump's bid to dismiss a lawsuit by Trump University students who said they were defrauded through its real-estate seminars. US District Judge Gonzalo Curiel in San Diego told a hearing he would take under consideration arguments on both sides in the case and issue a written ruling in the coming weeks. The 2013 lawsuit, one of three over the defunct Trump University venture, was filed on behalf of students who paid up to $35,000 to learn Trump's real estate investing 'secrets' from his 'hand-picked' instructors. The plaintiffs have sought class-action status.
