As President Donald Trump departed the White House on Thursday afternoon — his first time in public since announcing sweeping new tariffs that have jolted global markets and sparked recession fears — he likened the duties he imposed this week to a successful medical procedure.

While he voted in favor Wednesday of Trump retaining the emergency powers he used to impose his Canada tariffs, Sen. John Kennedy (R-La.) has some concerns.

The Senate passed a resolution to undo emergency declaration, but the measure has been blocked in the House.
