In her first major speech since leaving office in January, former Vice President Kamala Harris criticized President Donald Trump, spoke about the need for checks and balances, and brought up a viral video involving elephants.

Kamala Harris warned the U.S. government’s system of checks and balances was in danger of buckling, as Trump’s actions could trigger a “constitutional crisis.”

Kamala Harris had centered her closing argument of her unsuccessful presidential campaign on the dangers posed by Trump. These were her first major remarks since he took office.
