Former Vice President Kamala Harris on April 30 criticized President Donald Trump’s approach to the economy and warned of a constitutional crisis in her sharpest rebuke of the president since leaving the White House in January.

“Instead of an administration working to advance America’s highest ideals, we are witnessing the wholesale abandonment of those ideals,” Harris said in San Francisco during an address at the 20th anniversary gala for Emerge America. The organization recruits and trains Democratic women to run for office.

Harris, whose remarks came just one day after Trump marked his 100th day in office, said the new administration is trying to sow fear in Americans.
