Trump's backup tariffs face fresh legal hurdles

After the Supreme Court blocked his initial tariffs, Trump faces new legal challenges to replacement 10% tariffs under Section 122 and a balance-of-payments rationale; foes argue exemptions violate the law's uniformity, while supporters say the president has some leeway. With April hearings and a July expiration looming, a final ruling could come after the tariffs expire, leaving room for potential re-upping or tweaks.
