I am going to make two predictions, and am willing to take odds on them for a reasonable wager: First, George Santos will not be a Member of Congress for very long (probably the first to go), and certainly will not fill out his term; second, McCarthy will not finish the 118th Congress as Speaker, and may not remain a Member after his fall.
There will be a public and sustained outcry over the incapacitation of ethics investigations and the purpose and machinations of the "Committee to Obstruct Justice", especially if it is peopled with insurrectionists, as appears likely.
McCarthy will have no control over the Republican caucus, and that is going to be immediately fatal to his "Sqeakership". There has already been a complete fiasco regarding the House Rules.
On the other hand, don't expect moderate Republicans to exert any control, either. They talk a big game, but they elected McCarthy and voted for the House Rules. They will be easy to keep in line and silent.
