The watchdog, as part of his Clinton case review, found that Strzok and four other FBI employees sent “hostile” anti-Trump messages on bureau devices.
“A referral certainly is very serious and they will investigate the accusations if it’s serious enough,” retired FBI special agent and former national spokesman John Iannarelli told Fox News Thursday.
One former senior Justice Department official speculated on Thursday that Strzok might also be implicated in a separate inspector general’s review on the start of the Russia investigation.
But Horowitz’s testimony this week, meant to answer questions about the conclusion of the Clinton case review, revealed some of the specifics involved in the ongoing Russia case review, including the Strzok texts.
Strzok's attorney did not respond to Fox News' request for comment but in a statement issued in response to his removal from the office earlier this week said Strzok wants to continue to serve.
