Members of the moderate Republican Tuesday Group are trying to figure out how to move forward after Rep. Tom MacArthur, R-N.J., resigned as co-chairman early last week, which has caucus members wondering how they can flex their muscles in future battles, particularly over the budget and tax reform.

MacArthur’s resignation happened at their Tuesday meeting, sparking talks about what’s next for the group and how they should operate now that at least one major battle on healthcare is behind them.
