A recent report indicates that individuals such as Dr. Anthony Fauci and former Republican Representative Liz Cheney, having received pardons, can no longer invoke their Fifth Amendment rights to evade congressional testimony.
Furthermore, should they provide false statements to Congress, their pardons would not shield them from prosecution for that offense. Journalist Matt Taibbi remarked in a recent interview, ‘These pardons are fundamentally flawed. They have inadvertently simplified our ability to uncover the truth about ongoing matters.’
Once a pardon is granted, the individual is no longer able to invoke the Fifth Amendment. Should they be summoned before a grand jury or a congressional committee, they cannot claim their right against self-incrimination and are thus compelled to provide testimony.
