If the Senate were to secure those 60 votes and pass the war powers resolution, the chambers would have to work out differences in the text of the bill between the two chambers, which might require additional votes.

If both chambers pass identical versions of a war powers resolution, the measure would still require the president‘s signature to take effect — something that seems unlikely based on Trump‘s commitment to the war so far.

If Trump vetoes it, the House and Senate could override the veto only with two-thirds votes in each chamber, which is well above the support demonstrated so far. No war powers resolution has ever overcome a veto.
