The Justice Department’s decision to open a criminal investigation into E. Jean Carroll is more than another headline in Trump-world theater. It is the latest sign that the machinery of federal law enforcement is being pulled into personal politics, with a former president’s grievance now shaping the state’s agenda.

According to ABC News, the inquiry centers on whether Carroll committed perjury during her civil lawsuits against Donald Trump. The move follows a 2024 federal appeals court ruling that dismissed claims Carroll had lied, which makes the new investigation look less like a neutral correction than a search for a new angle against a longtime adversary.

The political meaning is hard to miss. Trump has long cast legal scrutiny of himself as persecution, then responded by aiming state power at perceived enemies once back in office. That pattern is now visible in the timing, the target, and the broader context of a White House that has made retribution an operating style rather than an isolated impulse.

The deeper danger is institutional. When prosecutors are seen as serving the president’s grudges instead of the public interest, the line between law enforcement and political enforcement begins to blur. That erodes trust not just in one case, but across the system.

The administration will argue that no one is above the law. But that standard loses force when it is applied selectively, and when the Justice Department’s urgency appears to mirror the president’s personal vendettas more closely than any coherent public-interest theory of justice.
