Democratic Sen. Elizabeth Warren hit back at critics who said her reading of a letter by Coretta Scott King about Alabama Sen. Jeff Sessions was an attempt to raise money and drum up attention for a possible presidential run in 2020.

Warren, D-Mass., said in an interview with CNN that she wasn’t trying to fundraise off the moment and isn’t thinking about 2020. Instead, she was trying to make a point that she feels Sessions is unfit to serve as attorney general.
