Former U.S. National Security Adviser Jake Sullivan, who served under the Biden administration, has broken his silence to criticize the Trump administration's first 100 days, warning of "terrible damage" to America's global standing. Initially silent to avoid being a "backseat driver," Sullivan now describes the nation's trajectory as "careening towards the cliff." He highlighted "terrible damage" to America's credibility and trust with allies, as well as harming the nation's political system, markets and innovation.
