cobble together 粗制滥造\Caucus n. 干部会议;核心会议\bipartisan 代表两党的\cutting deals\pick off
Pelosi's announcement comes before a bipartisan group of lawmakers in the Problem Solvers Caucus is set to meet with Trump on Wednesday to discuss the shutdown and border security. Democrats are trying to cobble together a solid base as the White House attempts to pick off members known for cutting deals.
Shortly before Pelosi's announcement, she and Minority Leader Chuck Schumer attended a closed-door caucus meeting with House Democrats, where Schumer told them to remain unified in their opposition to funding Trump's long-promised border wall.
