They don't need to new legislation: they just need to take back a lot of the power they have ceded over the years to the POTUS.
And frankly, the Dems are to blame too for this mess. They have ceded powers to the POTUS when he was a Demoracti they never should have ceded.
And I very skeprical that this will go beyound rhetoric. Each party screams about the abuse of power by the POTUS when they are in opposition, but clam up when one of their guys is in power.
And a major reason for this ceding of power is simple: C
