Muslim Brotherhood has a long history of violent killings & terrorizing opponents. Also MB has direct ties with most terrorist groups like Hamas.
A book by one of their prominent figures, Sayyid Qutb, called Ma'alim fi-l-Tariq is the bible for many terrorist groups.
The Muslim Brotherhood has shown that it is willing to engage in violence and killing of innocent civilians in order to invoke fear in the hearts of its opponents. This is terrorism.
We the people ask the US government to declare MB as a terrorist group for a safer future for all of us.
