Story highlights Rooney said the House Oversight Committee needs to "get to the bottom" of potentially politically compromised people in senior positions at the FBI

He called on Tuesday for a "purge" of officials at the FBI seeking to undermine the President

(CNN) Florida GOP Rep. Francis Rooney walked back the tenor of his call earlier in the week for a "purge" at the FBI, but maintained Wednesday that the bureau should oust individuals he views as politically compromised.

"It might be a pretty strong word. I'm not maybe the most nuanced political person in the world," Rooney said in a Wednesday interview with CNN's Brianna Keilar.
