Missouri Governor Jay Nixon will announce that St. Louis County law enforcement will be relieved of duty in Ferguson, which has been roiled by protests after the shooting death by police of an unarmed teenager, according to Representative William Lacy Clay.

“The governor just called me and he’s on his way to St. Louis now to announce he’s taking away St. Louis County police out of the situation,” Clay, a Missouri Democrat, said in a telephone interview. He added that Nixon may ask the U.S. Federal Bureau of Investigation to step in.
