Democratic presidential candidate and New Jersey Sen. Cory Booker called white supremacy a 'toxin' that is making the world less safe this weekend. 

Booker was campaigning in Iowa when he made the statement.

"There has been about 80-plus terrorist attacks since 9/11," said Booker. "The majority of them have been right-wing extremist groups."

Booker told the crowd that if he's elected president, his Department of Justice would investigate hate organizations.
