Wall Street is having another tough day amid anxiety over President Donald Trump’s often-changing tariff proposals. Trump delayed most tariffs on Mexican goods after talking with their president. But Canada's prime minister said retaliatory Canadian tariffs will remain as long as Trump leaves any U.S. tariffs in place. Trump issued what he called a “last warning” to Hamas to release all remaining hostages held in Gaza. Trump administration officials said talks between Washington and Kyiv were positive. And more Trump appointees face tough questions during Senate confirmation hearings.
