Senate negotiators are working to resolve thorny differences with leaders of the Southeastern and Big Ten Conferences over revisions to a bill designed to regulate college sports that sponsors want a vote on before the chamber goes on summer break next week. Bill sponsor Ted Cruz of Texas says the conversations are ongoing. Cruz and co-sponsor Maria Cantwell of Washington are pushing to bring the Protect College Sports Act to a vote before Aug. 7, the last day the Senate meets before going on break. Senators return for the second half of September, before breaking for all of October -- leaving little time remaining before the November midterms.
