The Senate is ready to start voting on amendments to the fiscal 2019 Defense spending bill, possibly including several that could stir spirited debate.

Senators have only agreed so far to vote on two relatively uncontroversial amendments to the the two-bill package that includes both the $675 billion Defense bill and the $179.3 billion Labor-HHS-Education measure. Those first two votes are scheduled for Monday evening.

On the horizon, though, are potential fights over President Donald Trump’s termination of others’ security clearances, U.S. support for the Saudi-led war in Yemen, procurement of warships that were not part of Trump’s massive Pentagon budget request, questions about winners and losers in the creation of a new Army command and, not least, federal funding for abortions.

Amendments along those lines have been filed, but Senate leaders have yet to announce which amendments will get votes.

“This process is not easy,” Majority Leader Mitch McConnell said in floor remarks Aug. 16. “On the floor, we need cooperation from both sides to process amendments, while resisting the temptation to turn the appropriations process into a free-for-all on all manner of policy issues. But this year, that is exactly what we are doing.”
