Sen. Cory Booker said President Donald Trump is “complicit” in the rise of violence by white nationalists and other domestic terrorist groups.

“He talks about terrorism all the time but to cut funding to investigate these domestic terrorist groups, these white supremacist groups, is making us less safe,” Booker said Wednesday. “And for him to fail to condemn Nazis or to even talk about white supremacy as a problem in this country to me that is being complicit in the violence that is happening. And I find that unacceptable and repugnant.”

Booker, who is running for president, spoke at a CNN town hall in South Carolina Wednesday night. He expressed concern about the rise of white supremacy and violence.

“You look at the majority of terrorist attacks since 9/11 the majority of them have been done by homegrown right wing extremist groups and the majority of those have been white supremacist groups,” Booker, a Democrat from New Jersey said.

Booker criticized Trump for cutting funding from the justice department that would allow for more thorough investigations into white supremacist attacks.
