There is an additional irony to how all this proceeded, in that Congress seldom ever moves to meaningfully limit the President’s powers in the foreign policy arena — see the blocking of Rep. Barbara Lee’s AUMF repeal amendment earlier in July — but on this rare occasion, when they have in fact limited the president’s powers, the impact is to constrain his ability to use non-military options to address problems, and effectively force him to take a more belligerent posture. Should this bill formally become law, Trump (or any future president) would be barred from modifying the expanded and codified Russia sanctions regime without approval from Congress.
