FERGUSON, Mo. (AP) — The embattled police chief of the suburban St. Louis town where a white officer’s fatal shooting of a black 18-year-old remains under investigation has criticized Attorney General Eric Holder’s recent call for “wholesale change” in the department.

Ferguson chief Tom Jackson tells the St. Louis Post-Dispatch that Holder’s comments in Washington this week were “irresponsible” while federal investigations into both Michael Brown’s Aug. 9 death and the broader Ferguson police operations are still going on.

Jackson said he is “low-hanging fruit” after a series of published reports suggesting he was being forced to step down to soothe department critics. The chief said he has no plans to resign.
