It was supposed to be Tax Day in America, but thanks to computer issues at the IRS, everyone gets another day to file. Taxes were still on the docket at the Supreme Court today though — the justices heard South Dakota v. Wayfair Inc. At issue is whether the online retailer and others like it should collect sales tax. We’ll follow the money. But first: Starbucks is closing down all 8,000 of its company-owned stores for one day next month to give its 175,000 workers racial bias training. The move comes after two black men were arrested at a Starbucks in Philadelphia when a manager called the police because they were sitting in the cafe without buying anything. We’ll talk about it. Plus: President Donald Trump is meeting with Japanese Prime Minister Shinzo Abe this week, and trade’s on the table. Japan’s one of several American allies and 2,200 companies looking for an exemption. We’ll look at who else is on the list.
