Lawmakers in at least 22 states are considering legislation to legalize sports gambling this year. Seven states joined Nevada and legalized it last year after the Supreme Court's decision. An Associated Press review of all sports gambling bills introduced this year — more than 100 so far — found high interest among lawmakers, primarily as a source of revenue, but also many questions about how legalized sports betting would be handled. Casino companies, sports leagues, fantasy sports companies and others are lobbying lawmakers in the hopes of getting the legislation tailored to their liking.
