Prepare for a serious brawl; & for most of these pork barrelling (no: they're not primarily budget cutting... stopping New Horizons will cost a fortune; because the development of all the way cool nuclear & SEP technology will cost much more than New Horizons itself; even without the additional cost of the mission) initiatives to get scrapped in the process.

Keeping the heat on the Congress - the White House is a dead loss in this & many other issues of intelligence - will give Mikulski the power to keep her Pluto mission flying; & the international threat to pay Russian components for ISS (& effectively side line NASA from the space station it mostly paid for) will keep the manned space budget high.

Just watch....
