Shortly after winning control of the House in 2022, Republicans vowed to use their newfound majority to investigate the Biden administration and crack down on its alleged weaponization of the federal government against conservatives, mainly former President Donald Trump.

But several rank-and-file lawmakers have also taken it upon themselves to protect the former president as he navigates legal troubles and federal investigations of his own.
