ABC's Jonathan Karl later asked Spicer to clarify whether Trump will demand that funding for the wall be included in the current spending bill.
Though he would not offer details, Schumer said the bipartisan group of negotiators involved in crafting the spending package were taking the signals from Trump and his team "at face value" and proceeding on the basis that funding for the wall would not be a part of the package.
"It's a golden opportunity for Trump to giant-foot-stomp (Democrats) and end this crap of a perennial, never-ending government shutdown paralyzing anything sensible being done with our budget and our economy", Limbaugh told his listeners.
But the president insisted on Twitter that he still supported the wall and that it would be built.
"Building that wall and having it funded remains an important priority to him". There was going to be a border wall, and at every rally he would shout out: "And who's going to pay for it?"
If no spending measure covering April 29 to September 30 is in place before 12:01 a.m. (0401 GMT) on Saturday, government funds will halt and hundreds of thousands of the country's several million federal employees will be temporarily laid off.
"The wall's going to get built, folks", Trump told reporters at the signing of an executive order on agriculture at the White House Tuesday.
President Donald Trump's 100th day in office will see the federal government shutdown if Congress can't come to a budget agreement by the end of the week.

In a phone conversation with Trump yesterday, Chinese President Xi Jinping called for all sides to exercise restraint. South Korean defense ministry officials and USA military officials could not immediately be reached for confirmation.
On Capitol Hill, meanwhile, lawmakers took Trump's apparent shift as a given and are moving forward in their discussions across the aisle with the assumption that the funding bill will contain appropriations for broader border security-including surveillance technology and personnel-as opposed to a physical barrier.
"Don't let the fake media tell you that I have changed my position on the WALL", Trump tweeted on Tuesday. "In case anyone has any questions, the wall's going to get built, and it's going to stop drugs and a lot of people from coming in that shouldn't be here".
At some point in the future it may well get built, but this has been a stark lesson in the difference between campaigning and governing.
In a conference call with reporters aimed at criticizing Trump's first 100 days as ineffective, party leaders said the biggest shutdown threat was from Trump's demand that the spending bill include funds for the barricade along the Mexican border. If Democrats thought their opposition to the border wall would demoralize the president, they are in for a rude awakening.
Republicans are also vetting proposed changes to their beleaguered health care bill that they hope will attract enough votes to finally push it through the House.
In his daily press briefing today, White House press secretary Sean Spicer told ABC News' Jonathan Karl that the administration is determined to begin planning for wall construction this fiscal year.
Trump was adamant that the wall will be built - but warned if it is not, the drug epidemic in the country will never be fixed.
