The Metropolitan Police Department in Washington, D.C., said on Friday that it was investigating U.S. Representative Cory Mills, a Republican representing a district northeast of Orlando, in connection with a report of an assault on a woman this week.

D.C. police are investigating a Florida representative after officers were called to a home for a report of an assault. Rep. Cory Mills has denied any wrongdoing. The alleged assault victim, Sarah Raviani, has also denied that any physical altercation took place between the pair.

MPD said the internal investigation will focus on department's "change in the initial classification of the offense," as well as why officers did not arrest Mills.
