Ian Brzezinski, an Atlantic Council senior fellow and former senior Pentagon official, said the incoming Democratic-controlled US Congress could push President Donald Trump toward tougher Russia sanctions and restored Ukraine aid. He spoke to TVP World, reported by Kyiv Post on November 5, 2026. Brzezinski argued that bipartisan cooperation could constrain Trump's approach to Moscow, though the president retains substantial constitutional authority over foreign policy. He also said Congress could help prevent cuts to US forces in Europe.
