Wray, however, said last week that he wouldn’t use the term “spying” to describe the FBI's monitoring of some Trump campaign members.

The Justice Department's inspector general is currently reviewing whether the FBI followed procedures in applying for a warrant to surveil former Trump campaign adviser Carter Page.

Republicans have said the FBI improperly relied on details from a dossier compiled by ex-British intelligence agent Christopher Steele for the warrant.

The surveillance activity was part of the early investigation into Russian election interference and links between the Trump campaign and Moscow that eventually spawned Mueller's probe, which ultimately did not find evidence of collusion.
