Thursday hearing with Peter Strzok expected to be contentious. After refusing to testify, FBI lawyer Lisa Page will testify Friday.
"Let me be clear, unequivocally and under oath: not once in my 26 years of defending my nation did my personal opinions impact any official action I took," Strzok is expected to say, according to a copy of his draft statement obtained by CNN. "(T)he fact is, after months of investigations, there is simply no evidence of bias in my professional actions."
