Large chunks of the federal government were shut down on December 22 after lawmakers and the president hit an impasse over Trump's demand that a bill to keep the federal government operational include money to help build a $23 billion wall along the USA border with Mexico.
Jared Kushner, Trump's son-in-law and a senior adviser, also attended the meeting at the White House, along with Homeland Security Secretary Kirstjen Nielsen and Mulvaney.
As IJR Red reported, Pelosi, who was elected speaker of the house on Thursday in the newly Democrat-run House of Representatives, sidestepped Tlaib's controversial comments and insisted it was "freedom of speech", adding that she's not in the "censorship business".
People familiar with the session but not authorized to speak publicly described Trump as holding forth at length on a range of subjects but said he made clear he was firm in his demand for $5.6 billion in wall funding and in rejecting the Democrats' request to reopen the government.
Transport Security Administration employee Brian Turner told the BBC he might have to look for another job if the shutdown continued.
"I thought we had come in to talk about terms that we could agree on, places where we all agreed we should be spending more time, more attention, things we could do to improve our border security", he told CNN's Jake Tapper.
Democrats have vowed they will not give Trump taxpayer money for the wall, especially since he said repeatedly during his 2016 campaign that Mexico would pay for it, which Mexican officials have often said they will not do.
House Armed Services Committee Chairman Adam Smith, meanwhile, said that while the president does have the authority to declare an emergency, any move toward that end would leave the administration "wide open" to a court challenge.
Democrats, however, warned the president would face immediate legal challenges if he tried to declare a national emergency to build a wall.

"This shutdown could end tomorrow and it could also go on for a long time", Trump said. I'm very proud of doing what I'm doing.
A Reuters/Ipsos opinion poll showed that 50 per cent of the public blame Trump for the shutdown and 7 per cent blame Republican lawmakers, against 32 per cent who blame Democrats. "This action is necessary so that the American people can receive their tax refunds on schedule".
Trump says he will not sign the bill until he gets the money for the wall.
Trump has already suggested his definition of the wall is flexible.
The White House switchboard and the call-in phone line to the White House are not operating due to the government shutdown, so it is unclear what calls he is referring to, of if any such calls actually occurred. "The president is interested in resolving this issue", Mulvaney said. "And Senate Republicans are just the right ones to intervene".
Earlier in the day, House Speaker Nancy Pelosi said impeachment is an "open discussion" and the findings of Special Counsel Robert Mueller must be weighed.
The Senate had actually reached bipartisan agreement on a budget but Mr Trump then refused to back it, demanding the funding for the wall.
