The Iowa Tribe of Oklahoma opened its new Harrah’s-branded casino in April. But plans for Harrah’s to take over casino management are stalled because of a vacancy at a federal watchdog. The National Indian Gaming Commission hasn't had a chairperson since January and President Donald Trump has yet to nominate a replacement. That’s left the commission unable to carry out enforcement duties or management deals like the one in Oklahoma. Industry leaders say the vacancy risks delaying business deals and weakening oversight. It also deprives tribes of a key advocate as prediction markets threaten to encroach on the $46 billion tribal gambling industry.

President Donald Trump is making a rare visit to California and Nevada to try to draw contrasts with Democrats on the economy and other issues. Trump wants to shore up support for Republicans in November elections that will determine whether his party keeps control of Congress. Trump is attending a Republican National Committee dinner at his golf club near Los Angeles on Tuesday. Before Trump's arrival, authorities revealed that a California man who was carrying ammunition and had a gun in his car had been arrested Sunday at the golf course. On Wednesday, Trump is slated to talk about the economy at a Las Vegas casino hotel.

New York officials have sued prediction market platform Kalshi for potentially billions of dollars, calling it an “illegal, unlicensed gambling operation” as the state seeks to halt its operations and force the company to forfeit its profits. New York joins a growing number of states filing lawsuits against Kalshi and other companies in a dispute with President Donald Trump’s administration over who regulates the fast-growing prediction market. New York's lawsuit was filed Friday in state Supreme Court in Manhattan. Kalshi and other platforms argue they are federally licensed and regulated, and states have no authority to govern them.
