Congressional Democrats moved on Monday to challenge President Donald Trump's decision to waive sanctions on Russia, introducing resolutions in both chambers aimed at reversing the relief. The effort followed anger from members of both parties over the waiver announced last week.

Senator Jeanne Shaheen of New Hampshire, ranking Democrat on the Foreign Relations Committee, and Representative Gregory Meeks of New York, top Democrat on the House Foreign Affairs Committee, led the push. They framed the waiver as a reward to Moscow that undercut Ukraine and American allies in Europe.

Trump's abrupt move drew criticism from Republicans and Democrats alike, but Republican leaders gave no indication they would schedule a vote. Senate Majority Leader John Thune declined to commit to floor time, and any resolution would face a near-certain presidential veto.

The measures invoke congressional review provisions governing sanctions relief, requiring the administration to justify the waiver. Democratic aides acknowledged the resolutions were unlikely to pass both chambers quickly, instead viewing them as a positioning move ahead of the November midterm campaign.

The standoff deepened tensions between the White House and lawmakers over Russia policy. Several Republicans privately expressed unease about the decision but remained reluctant to break with Trump publicly.
