Looking for sources

Alright I'm typing a paper for a Comp 2 class over corruption in the us government, and i was wondering if any of you out there knew of any good and valid sources that i could use for my paper. Not speculation as my teacher wont let that pass but hard evidence and fact. I'm trying to focus on lawmakers, senators, and even high federal officials.


Big Thanks in advance to those who help!!!!!!





I don't know if this is the right section, if its not then please move the right one.
