If Democrats win the House, and possibly the Senate, a result nonpartisan analysts call plausible, they would gain the power to bring new Ukraine aid to a vote and to push back on President Donald Trump’s deals easing pressure on Russia, Reuters reports in an analysis of how US foreign policy could shift.

The stakes are concrete. Trump has largely halted direct US aid to Ukraine, which lawmakers of both parties had backed, and its current supplies run from packages passed under his predecessor.

Weeks ago, he also waived the sanctions on Russian energy that Congress had written into law and struck a deal to bring Russian diesel back to the market, angering Republicans and Democrats alike.

What a Democratic Congress could do for Ukraine

With both chambers, Democrats could put new Ukraine aid on the floor, and given the bipartisan support such aid has drawn, it could pass with the two-thirds majorities needed to override a Trump veto.

Other steps could be taken, too. Representative Gregory Meeks of New York, in line to chair the House Foreign Affairs Committee if his party wins control, has already introduced bipartisan legislation to block Trump’s plan to return Russian diesel to the global market.

Democrats are also readier than Trump’s Republicans to rein in military spending. They blocked his request for an unprecedented 67% rise in the military budget, to $1.5 trillion, in the Senate, and many say they will try to restore the foreign aid he has withheld or canceled.

The limits of a slice of power

The leverage has limits. Even with both chambers, Democrats would still face a president who can veto, and overriding him would require two-thirds of each chamber. The pattern has already been visible in Iran: Trump launched that war on 28 February without congressional approval, and when a War Powers resolution passed with a handful of Republican votes, his administration ignored it.
