In October 2016 , Trump said that he would push for a constitutional amendment to impose term limits on members of Congress , so that members of the House of Representatives could serve for a maximum of six years and Senators for a maximum of twelve years . Trump also pledged to re-institute a ban on executive branch officials from lobbying for five years after leaving government service and said that he supported Congress instituting a similar five-year lobbying ban of its own , applicable to former members and staff . Under current " cooling-off period " regulations , former U.S. Representatives are required to wait one year before they can lobby Congress , former U.S. Senators are required to two years , and former executive-branch officials " must wait either two years or one year before lobbying their former agency , depending on how senior they were . " Trump has voiced his opposition to video game violence . After it was erroneously reported that the Sandy Hook shooter frequently played violent video games , Trump tweeted , " Video game violence & glorification must be stopped — it is creating monsters ! " Trump supports online gambling , based on the following reasoning : " This has to happen because many other countries are doing it and like usual the U.S. is just missing out . " A 2016 report in '' Scientific American '' graded Trump and three other top presidential candidates — Hillary Clinton , Gary Johnson , and Jill Stein — on science policy , based on their responses to a twenty-question ScienceDebate.org survey . Trump " came in last on all counts " in grading , with scientists and researchers faulting him for a lack of knowledge or appreciation of scientific issues
