House Speaker Nancy Pelosi, D-Calif., isn’t a member of the bipartisan team of 17 lawmakers appointed to negotiate a critical border security deal, but she is poised to wield more influence over the outcome than anybody else in Congress. That will make it nearly impossible for President Trump to win money for a wall along the Mexican border.

Pelosi, who regained the speaker’s gavel in January after eight years sidelined in the minority, emerged more powerful than ever last month after the 35-day partial government shutdown that ended when President Trump signed a short-term spending deal without a penny for the wall.
