What allegations are being made against Cash Patel during his FBI director confirmation process?

According to the clip, Cash Patel faces multiple serious allegations as he moves toward confirmation as FBI director. He is accused of already directing a purge inside the FBI bureau from the outside, suggesting he's inappropriately influencing the organization before his official confirmation. Additionally, Patel is alleged to have broken protocols during his time at the National Security Council. These allegations add to the controversy surrounding his nomination, despite apparent Republican support that may make his confirmation process more of a formality than expected.
