When Trump bypassed the Senate to name acting Cabinet members, clearly violating the law, they shrugged. When he gutted the ranks of inspectors general in a clear attempt to stifle genuine accountability of the executive branch, they barely protested.

Instead, many of them actively Trumpified themselves. In primaries, they vied with one another to prove their fealty to the Orange God King.
