Am I correct in thinking that a president DOES NOT have the constitutional authority to impose tariffs on any country? That is a power that congress has, not the president. If so, then why do we not hear such condemnations? What can congress do to stop these tariffs (where are the checks and balances)? When did this type of presidential abuse of power begin?
Congress has over time given presidents discretion to levy tariffs as a negotiating tactic. Like you, I think this was unconstitutional, but in general, federal courts have proven unwilling to keep Congress from delegating legislative authority to various organs of the Executive Branch.
