WASHINGTON (AP) — Congress is ending a chaotic session with a rare rebuff by Republicans of President Donald Trump. GOP senators are ignoring the outgoing president’s demand to increase the $600 COVID-19 aid checks to $2,000. They are poised to override his veto of a major defense bill. Trump ally Sen. Lindsey Graham of South Carolina is trying to bridge the divide. He says Congress could try again to approve bigger COVID aid checks after the new session opens Sunday. Senate Majority Leader Mitch McConnell says Congress has provided enough pandemic aid, for now. The stalemate is expected to drag into the weekend.
