Senator Collins

Senator Collins is a member of Sarah's group who used to be a senator of the small town they come from. When the aliens attacked, Collins ordered Sarah and the other policemen to go to his pffice and protect him and his closest people. Despite the fact that Sarah protested, she eventually agreed and abandoned the people of the city and hid inside his office. She and the other policemen got their jobs because Collins knew them, and did so by unworthy means. However, Sarah has sworn to do her job as well as she has to. After the attack subsided, the group remained under Collins' authority, since he evoked democracy every time a policeman (Sarah most of the time) spoke against his decisions. The other three policemen stood by him as well, making things even more difficult.
When Collins became a member of the group, he was a pain in the ass, since he abused democracy and used it to threaten anyone who spoke against him. He also had three policemen with him and often hit on any woman he saw, promising her privileges in order for sex, but he was eventually thrown out when Sarah admitted she took the job because of her being close to Collins (her father was in the same political party and close friend to Collins)
William then made an attempt to arrest him and remove him from his position, but the other policemen intervened and they and william's people pointed guns to one another. After a while though, Sarah intervened and convinced Collins to surrender, but one of the policemen shot her in the shoulder, before William put him down. After this, Collins stepped down until they made it to New York, where he worked underground to rise in power again. Along with Father Samuel, he rallied a big group of people to rise in power. 
Collins also had sex with Joleene whom he promised and gave lots of things in return. Danny found out about this and once more got repulsed at her. They got together later
Collins had a wife and a son who died during the invasion. His son was six years old
Regarding him, another man said "There does exist a good politician, the same as there exists an honorable thief"
