President Donald Trump is holding a "Make America Wealthy Again" event, during which he is expected to announce and reveal further details surrounding his "Liberation Day" tariffs that will roll out Wednesday.

Few details of the announcement are known prior, creating anxiety among the business community and global leaders.

The president's long-awaited tariff announcement will come on the same day Trump faces a possible rebuke from the Senate. Enough Republicans are expected to join Democrats on Wednesday in voting to end the emergency declaration enabling tariffs against Canada.
