WASHINGTON, May 9 — Democrats voted to rescue the Republican leader of the US House of Representatives yesterday after a right-wing lawmaker moved to topple him, plunging the already-divided party into fresh conflict ahead of November’s elections.

Under House rules, any single lawmaker can force a vote to oust Speaker Mike Johnson, and Marjorie Taylor Greene finally pulled the trigger more than six weeks after filing a “motion to vacate” his position atop the Republican majority.
