Why is Cash Patel's nomination as FBI Director facing scrutiny?

Cash Patel's nomination as FBI Director is facing scrutiny from Democrats who question his fitness for the role. Some have alleged that Patel has already initiated a purge within the bureau from the outside, suggesting he may be making personnel changes before official confirmation. Additionally, Patel is accused of breaking protocol during his previous position at the National Security Council. The Senate is holding a procedural vote to advance his nomination despite these concerns, highlighting the controversial nature of his potential appointment to lead the FBI.
