Sen. Bernie Sanders says Minnesota Senate contest is going to be a "tight race"

Sen. Bernie Sanders, who endorsed Abdul El-Sayed ahead of his victory in the Democratic primary, has also endorsed Lt. Gov. Peggy Flanagan in the Minnesota Senate race. He told "Face the Nation with Margaret Brennan" that contest is going to be a "tight race" because "she's being outspent 7-1" by her opponent, Rep. Angie Craig.
