Here’s what we’re following:Canada will announce retaliatory tariffs against the United States on Tuesday after relations deteriorated sharply, with President Donald Trump telling Canadian leaders to “fall in line” and Prime Minister Mark Carney accusing Washington of trying to subordinate Canada. Trump threatened new 50% tariffs on Canadian vehicles, auto parts and steel, while Carney said U.S. trade demands showed Washington wanted to “destroy our major industries.” On Tuesday, Trump claimed that he’s considering renaming Lake Ontario as “Lake America.”The fiery words from both sides show how U.S.-Canada relations have worsened since Carney walked away from trade negotiations with the Trump administration late Friday, triggering the president’s threatened 50% tariffs the next day on about $20 billion worth of Canadian goods.The Supreme Court on Monday cleared the way for Trump to move ahead with his executive order restricting mail-in voting, though it remains unclear how much his administration can implement before the fast-approaching midterm elections. Mail balloting has long been a favorite target for Trump, who has claimed that it breeds fraud despite strong evidence to the contrary and his own use of the voting method.Treasury Secretary Scott Bessent announced a new round of sanctions aimed at Iran on Monday and warned every country that does business with the Islamic Republic to sever those financial ties or face retaliation from the U.S. The announcement follows Trump’s pledge last week to unleash an “economic D-Day” against Iran, in an effort to sever it from the rest of the global economy.
