Senate Majority Leader Harry ReidHarry Mason ReidMcConnell not yet ready to change rules for Trump nominees The Hill's Morning Report — Sponsored by CVS Health — Trump’s love-hate relationship with the Senate Trump to press GOP on changing Senate rules MORE (D-Nev.) expressed frustration early Thursday afternoon saying that although progress has been made in pushing through the dozens of proposed amendments, many demands remain unsatisfied. 

“Progress is being made but not nearly enough,” said Reid. “[I] want everyone in the sound of my voice to understand that this cannot go on forever. We cannot have votes on all of these amendments that have been called up here. I hope every one would understand there has to be some give and take.”

Two traunches of amendments were already disposed of on the Senate floor early Thursday afternoon but by evening leaders were still unable to produce an agreement to alllow a third.

Reid drew larger and perhaps more serious connotations from the impasse, however, noting that the effort to push through the funding bill was an attempt to return to regular order after several years of an ad hoc budget process. 

“This was a noble experiment," he said. "I am part of it and I very much want it to succeed."
