Facebook wants to hire individuals with national security clearances, a decision motivated by the possibility that Russian actors may have manipulated its platform during the 2016 election, Bloomberg reported.

A source told the news service that Facebook believes that such workers can help its efforts in countering foreign actors trying to influence users and direct misinformation campaigns.

Such candidates are often former government and intelligence employees or contractors, Bloomberg reported. In the past, clearances were deactivated when an official left the government. The clearances can now carry over to the private sector, however, if an employee is still dealing with classified information. Facebook can reportedly ask that clearance statuses be reactivated.

Military contractors, consultants and information technology companies have also been known to seek out job candidates with security clearances.

The California-based company is facing pressure to crack down on foreign actors using its platform for influence campaigns. In September, it was revealed that Kremlin-linked actors had purchased $100,000 in political ads on its website.

Facebook has since released the 3,000 ads to congressional investigators. The top Intelligence Committee Democrat, Sen. Mark Warner (Va.), has said that those ads are just the "tip of the iceberg," and that he expects subsequent investigations to reveal more information.

The company is trying to ramp up its efforts to stop influence campaigns on its platform. Facebook CEO Mark Zuckerberg pledged to add 250 people to help beef up election integrity. The company will also hire another 1,000 employees to review and, if necessary, remove ads that violate its policies.

Lawmakers are set to press company officials further during Senate and House intelligence committee hearings scheduled for Nov. 1.
