As midterm elections approach, Democrats are gearing up to investigate former President Trump’s trade deals and scrutinize Wall Street and cryptocurrency firms for potential corruption. Business leaders are bracing for a wave of probes as Democrats eye control of the House, with an emphasis on oversight concerning costs and corporate ties to Trump. Inside the party, there are divisions over how aggressively to pursue investigations against corporate allies of Trump, with some expressing concerns about the implications for democracy. The anticipated surge in congressional probes is prompting businesses to prepare for the scrutiny that comes with a possible Democratic majority.
