The broader negative impact of the shutdown on the U.S. economy may be double what was projected, White House economists confirmed on Wednesday, the 26th day of the political standoff.
Meanwhile, thousands of employees have been called back to work without pay because of the risks posed for their agencies if, for example, airports continue to run with fewer aviation safety inspectors or the IRS heads into tax season down almost 60 percent of its workforce.
On the political front, no high-level talks between Democratic congressional leaders and President Donald Trump were scheduled over the president's demand for billions in funding for a border wall that Democrats refuse to agree to. A bipartisan group of rank-and-file House members did meet with the president mid-morning.
Here's a look at the effects.
The White House said a bipartisan meeting with members of the House Problem Solvers Caucus -- including seven Democrats, Reps. Josh Gottheimer, Thomas Suozzi, Vincente Gonzalez, Anthony Brindisi, Dean Phillips, Max Rose, and Abigail Spanberger -- met at the White House to sit down with Trump in the Situation Room Wednesday morning about the shutdown. Entering the meeting, the members said they planned to tell the president that the conversation about "some of our country's toughest problems" can "only begin in earnest once the government is reopened."
"We accepted the White House’s invitation to meet today to convey that message," a group statement read.
White House press secretary Sarah Sanders said in a statement after the meeting that it was "constructive."
“The President and his team had a constructive meeting with bipartisan members of the problem solvers caucus. They listened to one another and now both have a good understanding of what the other wants. We look forward to more conversations like this,” Sanders said.

In a letter to the president, House Speaker Nancy Pelosi proposed the delay saying the U.S. Secret Service and the Department of Homeland Security, the agencies designated to provide security for the Jan. 29 event, have not been funded for 26 days.
“Sadly, given the security concerns and unless government re-opens this week, I suggest that we work together to determine another suitable date after government has re-opened for this address or for you to consider delivering your State of the Union address in writing to the Congress on January 29th,” Pelosi wrote.
Hours after Pelosi's letter became public, there was no response from the White House, but Homeland Security Secretary Kirstjen Nielsen pushed back in a tweet against the implication that the shutdown has harmed the department's ability to secure the event.

A White House spokesperson confirmed early Wednesday that the administration has updated its projection of how much impact the ongoing partial government shutdown is having on the U.S. economy -- doubling the projected negative impact on growth. The increase was first reported by the New York Times.
The estimated impact is that the ongoing shutdown is shaving 0.13 percentage points off quarterly economic growth each week it continues, according to the White House official, and the updated model changed to include the estimated impact from contractors that are not working because of the shutdown – a number they said is harder to estimate -- in addition to furloughed federal workers.

After it was announced Tuesday that tens of thousands of IRS personnel would return to work to process refunds, along with air traffic controllers and food inspectors, the Agriculture Department said Wednesday it would recall about 2,500 employees to process farm loans.
The latest estimate of workers required to report to duty without pay was 450,000 as of Friday, according to the office of Democratic Sen. Patrick Leahy, vice chair of the Senate Appropriations Committee. The tens of thousands of workers recalled this week is likely to push that number closer to a half a million, assuming the shutdown continues through the end of the month.

Tim Kilcoyne, a lead chef with the Jose Andres' non-profit World Central Kitchen, said he found it strange to open a cafe and restaurant already fully furnished and with a ready-to-go kitchen, not to mention one surrounded by bustling businesses and busy streets. Here in Washington, the problem is not a fire or a flood -- instead, he and other volunteers have arrived to help feed some of the 800,000 government employees who are still without a paycheck on day 26 of the longest-ever government shutdown.
“Whether its activation for a natural disaster or a human disaster — we’re here to support, here to help,” Kilcoyne said.
The pop-up, which opened on Wednesday, is called #ChefsForFeds and will be open from 11 a.m. to 6 p.m., seven days a week, to provide federal workers in the nation's capital with free meals at its location on Pennsylvania Avenue just down the street from both the White House and Capitol.
Sen. Lindsey Graham, a Republican and frequent ally of the president, said he and a bipartisan group of senators would ask Trump to go along with a short-term measure that would reopen the federal government, with a promise that within a "few weeks" they might be able to reach a viable solution that would meet the president's border security needs, the senator from South Carolina told reporters on Capitol Hill Tuesday night.
"I’m hoping in the next 24 hours there will emerge a group of Republicans and Democrats who will basically ask the president jointly to give us a few weeks to work on this, with you, to see if we can produce a result in the Senate," Graham said, later adding that he couldn't guarantee an outcome in that time but "can pretty well guarantee you’re getting nowhere quick doing what we’re doing."
"I would ask the president, if that does come forward and there’s a critical mass of Republicans and Democrats asking for a period of time to work on this a short term CR, the president strongly consider giving us that opportunity," he said. "If that doesn’t work, then you can act through executive power saying I did everything I could," Graham said, referring to Trump's threats to fund a border wall by declaring a national emergency through an expansion of executive power.
Trump had said Monday that he had rejected Graham's idea, which Graham first proposed over the weekend.
Graham gave credit to his colleagues across the aisle, who he said will cooperate on border security but want to be able to hold up their end of the deal.
"There are plenty of Democrats who are willing to help the president meet his priorities in a reasonable fashion if they get something, too," Graham said.

Andrew Wheeler, Trump's nominee to take over as head of the Environmental Protection Agency, faced questions about the impact of the government shutdown on EPA's work and employees on Wednesday.
Wheeler confirmed in the hearing that some EPA policies have been delayed because of the shutdown, including a management plan to deal with a class of chemicals known as PFAS that contaminate groundwater and drinking water in some parts of the country. Wheeler said a plan to manage the chemicals and set limits for drinking water was set to be announced next week but will now be delayed.
Last May, the EPA said the management plan would be released in fall 2018 and that the agency would move to officially label the chemicals as "hazardous."
He also told senators the agency will have to bring back staff to meet court-ordered deadlines on other rules like regulations on lead in dust.
Democrats also raised concerns that Wheeler's nomination was being pushed through during the shutdown even though he could continue serving in an acting capacity for much of the year.
A protester stood up as Wheeler began his remarks to "object" the hearing was being held during the shutdown. More could be heard in the hallway outside the hearing room changing "shut down Wheeler, not the EPA."

The IRS will require some 46,000 employees to work without pay throughout the upcoming tax season to ensure returns are processed and refunds are mailed, the agency announced Tuesday in an updated plan for the government shutdown. That represents almost 60 percent of its 80,000-person workforce.
And while the IRS will be adding staff to answer some questions via telephone "in the coming days," the agency said, it's warning Americans to expect "heavier call volume" and "longer wait times." Walk-in assistance centers also will remain closed, including those offices intended to help people who are victims of identity theft and are required to visit an IRS office to establish their identity.
What will remain in effect is the requirement that people pay their taxes on time, although the agency said it won't conduct any audits during the spending lapse.

Unpaid federal workers and contractors have started selling personal property, creating small businesses and spending more time with old friends.
Working for the Coast Guard was always Albert Waterford Jr.'s dream job. The disabled veteran enlisted for two decades and, after his retirement, went back to work for the service as a civilian. His wife, Kate Wells Waterford, is a small business owner who trains horses. For those in the Coast Guard, the furlough has affected them differently because service members in other branches of the U.S. military fall under the Defense Department, for which funding has been approved.
The Waterfords hoped to receive their normal three paychecks this week: one for Albert's retirement from the Coast Guard, one for his job as a civilian and an additional check for his disability from the Veterans Affairs. But because of the shutdown, the couple has started a "furlough sale" to supplement lost income -- selling saddles, halters, bridles and items on social media.
"I called it a furlough [sale] because it is more of an urgency now," Kate Waterford said. "It's really made us re-evaluate our whole lives."

A federal judge on Tuesday denied requests from unions representing air traffic controllers and other employees required to work through the government shutdown that they either be paid or have the option to skip work while missing paychecks.
U.S. District Judge Richard Leon ruled to keep the status quo, saying that an order allowing employees considered essential to skip work would be "chaotic" in a best-case scenario and "catastrophic" at worst.
Lawyers representing the National Air Traffic Controllers Association had sued the Trump administration to get their controllers, thousands of whom continue to work and just missed a paycheck, be paid while working during the shutdown in order for them to remain "laser-focused" on their job guiding more than 40,000 flights through the nation's airspace every day.
