Kansas House Federal and State Committee Testimony 
On February 8, 2011, in testimony given before the Kansas House Federal and State Committee, Rep. O'Brien told of a time she identified a person as an undocumented immigrant based only on their "olive complexion," stating as follows:
Rep. O'Brien: "...My son who’s a Kansas resident, born here, raised here, didn’t qualify for any financial aid. Yet this girl was going to get financial aid. My son was kinda upset about it because he works and pays for his own schooling and his books and everything and he didn’t think that was fair. We didn’t ask the girl what nationality she was, we didn’t think that was proper. But we could tell by looking at her that she was not originally from this country."
Rep. Gatewood: (D-Topeka) "Can you expand on how you could tell that they were illegal?"
Rep. O'Brien: "Well she wasn’t black, she wasn’t Asian, and she had the olive complexion."
