Since Kash Patel, who is very loyal to the country's president Donald Trump, took over the role as head of the FBI, the use of lie detector tests has increased, according to two sources for New York Times.
The agency has previously used lie detectors to, among other things, find out if an employee is loyal to their country or can keep secrets.
But in recent months, the tests have become more common. Questions have also been about the FBI's top boss, according to the sources. It is supposed to be about tens of people, with higher positions, who have been given the lie detector tests, according to several sources. On the other hand, it is unclear how many have been asked questions specifically about Patel.
An FBI employee's loyalty is to the constitution, not the boss, says former agent James Davidson, who worked at the agency for 23 years, to the newspaper.
