"I support the Senate budget resolution because it provides a path forward on tax reform," said Sen. John McCain (R-AZ), who still wants GOP leaders to add more money to the budget outline for military needs.
Still not ready to commit to the budget or tax plans was Sen. Rand Paul (R-KY), who lobbed a series of pointed jabs at both McCain, and Sen. Lindsey Graham (R-SC), accusing them of trying to use budget gimmicks to funnel more money to the Pentagon, instead of finding ways to restrain spending.
In a first test vote, the Senate voted 50-47 in favor of beginning debate on the budget framework for 2018, which would balance the budget by 2026. A House budget outline would achieve that a year later.
No Democrats joined with Republicans to begin the Senate debate, as right now, the White House faces a difficult task in getting any Democratic lawmakers to endorse the President's budget or tax plans.
"It's going to be hard to get the Democrats, because they're obstructionists, and they vote in blocks," the President said in his Tuesday night speech.
If no Democrats cross party lines on taxes, that makes it all the more important for the GOP to stick together in the Senate, or the GOP could face the same outcome as on health care reform.
No legislative language for a tax reform plan has been released as yet by the GOP. Lawmakers don't expect to see all the details until next month.
