On Friday, the State Department released a batch of emails that revealed the top Hillary Clinton aide forwarded State Department emails and passwords to her personal Yahoo email account before every Yahoo account was hacked.
Several documents marked "classified" were also found on a laptop belonging to Abedin's estranged husband, Anthony Weiner.
On "Fox & Friends First," Fitton agreed with President Trump that it appears former FBI Director James Comey and others at the bureau declined to seriously investigate Clinton or her aides' potential security issues.
Crooked Hillary Clinton’s top aid, Huma Abedin, has been accused of disregarding basic security protocols. She put Classified Passwords into the hands of foreign agents. Remember sailors pictures on submarine? Jail! Deep State Justice Dept must finally act? Also on Comey & others

"Presumably, these four or five documents that were uncovered on Friday were known to the FBI at the time, but they let it go," Fitton said. "Remember, there was other classified material they already knew about, so it was just outrage on top of outrage in terms of the failure of the FBI and Justice Department to follow up on this."
Fitton said President Trump should demand the Justice Department conduct a "damage assessment" to see whether national security was put at risk given the sensitive materials discovered on Weiner's laptop.
He said Trump's appointees are making "fear-based" decisions because they do not want to go up against the "Clinton machine." Fitton ended by saying Abedin's emails are key to the pay-for-play investigation of the Clinton Foundation, since she was the "go-between" for favors.
