Ron Johnson Makes Excuses For Trump Shooter?

During a Senate hearing looking into the Trump shooting, Senator Ron Johnson (Q-Moscow) was questioning FBI Deputy Director Paul Abbate on why the agency was considering domestic terrorism as part of their investigation:

ROJO: Deputy Director Abbate, you said this is an assassination attempt and domestic terrorism. It's obviously an assassination attempt. Why make the distinction? What is different about that?

ABBATE: We think it's important to cover all the possibilities here in the reality of what we're dealing with.
