NEW YORK (AP) — Stocks are falling today, with the Dow industrials down 500 points in afternoon trading as investors worry about fallout from steep tariffs on steel and aluminum imports. Stocks were higher earlier in the day after Federal Reserve Chairman Jerome Powell appeared to calm one of the market's main worries when he said that he does not see inflation in workers' wages "at a point of acceleration." But stocks slid in the afternoon after President Donald Trump told steel and aluminum executives that he'll impose tariffs on imports next week.

WASHINGTON (AP) — Some members of Congress are warning that the new tariffs on steel and aluminum could launch a trade war that could hurt other industries. Kansas Republican Sen. Pat Roberts says tariffs always bring retaliation -- and he says "agriculture is the number-one target." And Republican Sen. Orrin Hatch of Utah says he doesn't think this is "the way to go."

UNDATED (AP) — Kroger is raising the minimum age to buy guns at its Fred Meyer stores. It's the third major retailer to place restrictions on gun sales that exceed federal law. Like Walmart and Dick's Sporting Goods a day earlier, Kroger says it will immediately limit gun and ammunition sales to people 21 and older. The nation's largest grocery chain says recent events show that gun retailers need to take action.

ATLANTA (AP) — The Georgia Senate has approved a sweeping tax bill that punishes Delta Air Lines for cutting business ties with the National Rifle Association. The measure, which was stripped of a jet-fuel tax break, passed the GOP-dominated Senate 44-10, with only Democrats opposed. The Senate's presiding officer is Republican Lt. Gov. Casey Cagle, who vowed Monday to stop any tax break that would benefit Delta. It sparked a showdown at the state Capitol between gun-rights supporters and one of Georgia's largest private employers.

UNDATED (AP) — Uber is driving deeper into health care by offering to take patients to their next medical appointment, in every U.S. market where it operates. The ride-hailing service says its Uber Health business will handle rides set up by doctor's offices or other health care providers and then bill that business, not the patient, for the service. It says rides can be set up within a few hours or days in advance. Patients won't need access to a smartphone to use the service.
