As the speaker of the House finally allows a vote to go forward on aid, the GOP’s internecine warfare is tearing apart the party

Republican divisions over military support for Ukraine were long simmering. Now, ahead of Saturday’s extraordinary vote in Congress on a foreign aid package, they have erupted into open warfare – a conflict that the vote itself is unlikely to contain.

Mike Johnson, the speaker of the House of Representatives, triggered an all-out split in his own party’s ranks last week by finally agreeing, after months of stalling, to a floor vote on the $95bn foreign aid programme. Passed by the Senate in February, it contained about $60bn for Ukraine, $14bn for Israel, and a smaller amount for Taiwan and other Pacific allies.
