Peaceful protests are one thing, this is a whole other level. If they disrupt or intimidate congressmen arrest them and their leaders. Charge them as domestic terrorists under The Patriot Act:

Section 802 of the USA PATRIOT Act (Pub. L. No. 107-52) expanded the definition of terrorism to cover "domestic," as opposed to international, terrorism. A person engages in domestic terrorism if they do an act "dangerous to human life" that is a violation of the criminal laws of a state or the United States, if the act appears to be intended to: (i) intimidate or coerce a civilian population; (ii) influence the policy of a government by intimidation or coercion; or (iii) to affect the conduct of a government by mass destruction, assassination or kidnapping. Additionally, the acts have to occur primarily within the territorial jurisdiction of the United States and if they do not, may be regarded as international terrorism.
