Senate security regarding General David Petraeus testimony

Yesterday, two members of Code Pink stood up and yelled during General David Petraeus testified. These two women were dressed all in pink. The same thing happened on Tuesday. It looked like the same two women. I thought that Ike Skelton had promised on Monday that these two women would be prosecuted to the full extent of the law. Whatever penalty these two women faced, how is it that these two women got into the hearing. It is my understanding that the audience had to get passes to attend the hearing. Why were these two women allowed in? Why did the Democrats want them to attend? Why does the press ask the Democrats why they keep letting these women in the hearing rooms?
