"One side was to blame" - Blumenthal

[_Jersey Girl]

Sen. Richard Blumenthal (D-CT) called President Trump out for blaming the violence in Charlottesville, Virginia, on both sides of the conflict, saying, "one side was to blame."

If you are someone who agrees with the above statement (the video is very short if you want to view it), I would like to know why one side was to blame, what they are to be blamed for and why?

Thanks folks.
