SEC enforcement chief exits amid scrutiny of market moves tied to Trump week

The Securities and Exchange Commission enforcement chief resigned after repeated clashes with agency leadership over the handling of major investigations. Reuters cited disputes that involved a probe connected to crypto backer Justin Sun and other high-profile matters. The resignation coincided with commentators claiming market moves followed Donald Trump's Iran-related announcements, raising questions about possible market manipulation. The exit matters because it weakens the SEC's enforcement posture during politically charged trading and will intensify scrutiny of how cases tied to political figures and crypto investors are handled.
