Lawmaker attacked in England
CNN —  

After British lawmaker Jo Cox was killed, her husband called on supporters to unite against hatred.

In a statement released Thursday, Brendan Cox said:

“Today is the beginning of a new chapter in our lives. More difficult, more painful, less joyful, less full of love. I and Jo’s friends and family are going to work every moment of our lives to love and nurture our kids and to fight against the hate that killed Jo.

“Jo believed in a better world and she fought for it every day of her life with an energy, and a zest for life that would exhaust most people.

“She would have wanted two things above all else to happen now, one that our precious children are bathed in love and two, that we all unite to fight against the hatred that killed her. Hate doesn’t have a creed, race or religion, it is poisonous.

“Jo would have no regrets about her life, she lived every day of it to the full.”
