Rep. Anna Paulina Luna, R-Fla., is resigning from the House Freedom Caucus, she announced in a letter to fellow conservatives on Monday.
It's the latest escalation in her fight against House GOP leaders and a small group of members on the right flank of their conference over the issue of proxy voting. Luna has teamed up with Democrats and several other Republicans on a mechanism aimed at forcing consideration of legislation that allows new parents in the House to vote remotely for 12 weeks around their baby's birth.
"I have consistently supported each of you, even in moments of disagreement, honoring the mutual respect that has guided our caucus," Luna wrote. "That respect, however, was shattered last week."
