"If Democrats refuse to work with us to tackle this national priority over the next few weeks, President Trump will do what is necessary to protect America," said Sen. David Perdue (R-GA), a key Senate ally of the President.
"Compromise is important, but not required, to secure our border and protect American families," added Rep. Mark Meadows (R-NC), maybe the closest Trump ally in the House.
The decision by Mr. Trump to allow the government to be funded capped five weeks of turmoil for 800,000 federal workers, as they missed a second paycheck on Friday, and will likely have to wait well into next week to receive their back pay.
After watching some of the news coverage about his latest moves, President Trump did not seem pleased.
"This in no way was a concession," the President tweeted Friday night, even as he did what Democrats wanted.
The statements of the President and the White House presented negotiators with an ultimatum of sorts, even before they began their work on border security funding.
"The President has agreed to our request to open the government and then debate border security," said Senate Democratic Leader Charles Schumer, as President Trump agreed to do exactly what Democrats had been calling for as a way to end a 35 day partial government shutdown.
"I hope over the next three weeks we can bridge our differences with a common goal to protect our country and end the humanitarian crisis, while keeping government open," said Rep. Tom Graves (R-GA), one of the House GOP negotiators.
Many Democrats alternated between mocking Mr. Trump and condemning his actions, arguing he had needlessly put thousands of federal workers through financial stress and strain with the shutdown - only to finally back off his demand that the government would not be funded until Congress approved money for his border wall.
"No one should applaud his recent actions - he created the crisis," said Rep. Dwight Evans (D-PA).
"Americans don't care whether or not you call your speech a concession," said Rep. Ted Lieu (D-CA). "No President should ever threaten to hurt, or actually hurt, Americans as a negotiating tactic."
"Holding federal employees’ livelihoods hostage in order to get Congress to meet an unreasonable border policy demand was always a bad idea," said Rep. Steve Cohen (D-TN).
More moderate Republicans also said the shutdown should not have been an option for the President.
"Ultimately, this shutdown never should have happened," said Sen. Lisa Murkowski (R-AK).
