WASHINGTON (AP) — Top Democrats have abruptly postponed an expected House vote on their 10-year, $1.85 trillion social and environment measure. The decision Friday came as infighting between progressives and moderates once again sidetracked the pillar of President Joe Biden’s domestic agenda. In a bid to hand him a needed victory, leaders prepared to try pushing an accompanying $1 trillion infrastructure measure through the chamber and to his desk. Progressives threatened to vote against it, continuing their demand that the two bills be voted on together. House Speaker Nancy Pelosi says the broader legislation is historic and “hence, challenging.”
