WATCH: Civil Rights Leader Refuses to March With Bush

Diane Nash, a leader and strategist of the student wing of the 1960s civil rights movement, refused to march in Selma on Saturday because former President George W. Bush also attended the event, which celebrated the 50th anniversary of the famous nonviolent protest.

In an interview with Roland Martin, Nash said: 'I refused to march because George Bush marched .... I did not, when it was apparent that he was going to be part of it.

"The Selma movement was about non-violence and peace and democracy, and George Bush stands for just the opposite -- for violence, and war and stolen elections. And George Bush's administration had people tortured. So I thought that this was not an appropriate event for him. I'm also concerned that the legacy of the Selma movement, which stands for nonviolence, will be confused and so I did not wish to be part of something that included him. ... George Bush's presence is an insult to me, and to people who really do believe in nonviolence."
