Nixon told the Post-Dispatch on Tuesday that he has been frequently in contact with local officials and the White House but has not had time to do the same with the Missouri congressional delegation.

The White House said its response to the Brown shooting began on Aug. 10, the day after the incident, when Department of Justice Community Relations Service employees were sent to Ferguson to “open lines of communication between protesters and local authorities.”

The next day, Aug. 11, Holder announced the DOJ would conduct a “fulsome review” and a “concurrent, federal” investigation of the shooting.

Obama received briefings on the Ferguson situation from Holder and Jarrett last Wednesday and Thursday. On Thursday, Nixon and Obama talked, and the president “expressed his concerns over the violent turn of events on the ground,” the White House account read. Obama later that day delivered a statement calling for peace and calm.

That same day, Holder spoke with Brown’s family and promised a “full, independent civil rights investigation,” according to the White House.

Holder also talked with both McCaskill and Blunt on Thursday. Thereafter, McCaskill and Holder independently expressed concern about “militarization” of the law enforcement response in Ferguson.
