The FBI on Wednesday provided separate “voluntary awareness briefings” about foreign spies to low-level staffers for both major presidential campaigns, ABC News reported.

The agency noted the meetings were “not precipitated by any particular [known] threat” and more of a reaffirmation of “standard best practices.”

The meetings come amid increasing suspicion about the illicit role of foreign intelligence agencies in this year’s election — particularly Russia.

Both campaigns have hired companies to help defend against attacks from foreign intelligence agencies. Both are believed to have been targeted by Russia, but there are no reports either campaign has been breached.
