Former Attorney General Michael Mukasey pushed back Thursday on the final report issued by Justice Department Inspector General Michael Horowitz on the handling of the Hillary Clinton email investigation. 

Horowitz concluded that the FBI's handling of the Clinton and Russia investigations was not motivated by political bias, though he singled out former FBI Director James Comey for harsh criticism and referred five other bureau employees for potential disciplinary action.

Most notably, Horowitz found that anti-Trump text messages between FBI agent Peter Strzok and FBI attorney Lisa Page "potentially indicated or created the appearance that investigative decisions were impacted by bias or improper considerations."

Mukasey, who served as the nation's top law enforcement officer from 2007 to 2009, said on "America's Newsroom" that Horowitz did a good job of reviewing a lot of detailed material, but he took issue with the conclusions he reached. 

"They counted all the trees, the question is whether they commented sufficiently on the existence of a forest. In my view, they didn't," he told Bill Hemmer, adding that Strzok and Page were influential within the FBI, not "street-level agents."

He argued that texts between them not only showed bias against then-candidate Trump, but evidence that their personal animus affected decision-making on the Clinton case. 

Mukasey said if Strzok were his client, he would not let him testify before Congress. 

House Judiciary Committee Chairman Bob Goodlatte (R-Va.) said Tuesday that a subpoena could soon be issued to Strzok, seeking his testimony as early as next week.
