McCaskill's office announced that she will speak with Attorney General Eric Holder about the "unacceptable" situation in Ferguson.
The senator on Wednesday spoke with the assistant attorney general for civil rights at the Department of Justice.
"As we continue to grieve for Michael and his family, I’m working to make sure the federal piece of this investigation is fair, transparent, and moving forward without delay," she said in a Wednesday statement. "As it proceeds, I’ll be remaining in close touch with the Department of Justice, and am reaching out personally to local elected officials and religious leaders, to keep monitoring the painful events on the ground in Ferguson."
According to LA Times reporter Matt Pearce, McCaskill drew cheers from the crowd at a church in Missouri on Thursday while discussing the police response to the protests.
