They also offered praise for Comey, referring to him as "brilliant."

“God he is SO good,” Strzok said. “I know,” Page responded. “Brilliant public speaker. And brilliant distillation of fact.”

Those texts have also fueled accusations among GOP lawmakers that Mueller's probe is tainted by partisanship.

A handful of Republicans have said their back and forth reveals bias against the president within top levels of the government.

Some GOP lawmakers have particularly homed in on the fact that the two officials were involved in the federal investigation into whether Clinton mishandled classified information with an email server as secretary of State as well as Mueller's probe into possible links between the Trump campaign and Russia.

Trump fired Comey last year. In recent weeks, Comey has taken to Twitter to comment on various political events.
