"It was a really unusual meeting", Mulvaney said on NBC's "Meet The Press".
President Donald Trump has said he will veto any spending bill to fund the government agencies affected by the shutdown if the legislation does not include $5 billion toward his long-promised wall along the USA southern border. "He's not building a wall anymore", that should help us move in the right direction", Mulvaney, who is also the head of the Office of Management and Budget, said.
Next week, House Democrats will begin passing individual appropriations bills to re-open all government agencies, starting with the appropriations bill that covers the Department of the Treasury and the Internal Revenue Service.
"It was productive and beneficial to have Secretary Nielsen finally be able to outline the crisis at the border in detail without interruption, given her prior efforts were cut off by Democrat leaders", Lauren Fine, a spokeswoman for House Republican Whip Steve Scalise, said in a statement.
"I'm actually heavily involved with it", he said, dodging the question. Trump is demanding any funding to keep the federal government operational also include $5.6 billion to begin building a $23 billion a wall along the U.S. border with Mexico.
According to a source familiar with the Friday meeting, Mr. Trump initiated the talks - held for the second time this week in the White House Situation Room - by lambasting the shutdown impasse and again demanding $5.6 billion for border security, which he declared to be the minimum figure he needed to build the southern border wall he has been promising since his presidential campaign. But Trump has repeatedly said he will not budge without money for the wall. "Administration officials refused", the Democratic source contended. "I think that's... by intention".
Despite pitting blame on Democrats, the president reiterated that he remained "proud of doing what I'm doing".
President Donald Trump says he doesn't expect anything to come out of a second day of negotiations between top administration officials and senior congressional staff trying to end the partial government shutdown now in its third week. Democrats reported little progress; Trump framed the weekend talks as a key step forward.
As the shutdown drags on, some Republicans are growing increasingly nervous.
Would Mulvaney personally support Trump declaring a state of emergency?
Trump repeated the false claim to reporters Friday that Mexico was paying for the wall through the newly-negotiated trade agreement, which is now called the United States-Mexico-Canada Agreement.
A national emergency is one of the conditions under which Pentagon funds could be used to build the wall.
Mr. Trump said the federal workers who are furloughed or working without pay would want him to "keep going" and fight for border security.
