A group of five small U.S. businesses sued President Donald Trump, challenging his recent tariff hikes as unconstitutional, according to CNBC. The lawsuit argues that Trump unlawfully invoked emergency powers to justify the tariffs, bypassing Congress’s authority to impose taxes. The Liberty Justice Center, which represents the plaintiffs, argues that Trump's tariffs are severely harming small businesses nationwide. The lawsuit claims the trade deficit used to justify the tariffs does not constitute a real emergency.
