The White House is expressing support for Chicago Mayor Rahm Emanuel as he struggles with the fallout from a police shooting.
A White House spokesman says Emanuel has demonstrated a "personal commitment" to reforming the city's police department.
Emanuel fired the police superintendent and formed a task force to study police accountability in the aftermath of the release of a 2014 video showing a white police officer shooting a black teenager 16 times.
The case has sparked protests and calls for Emanuel's resignation. Emanuel served as Obama's first chief of staff.
President Barack Obama has seen the video, but does not want to appear to be interfering in a potential federal investigation.
