(WASHINGTON) — The House select committee investigating the Jan. 6 Capitol attack issued 11 subpoenas Wednesday to organizers of the pro-Trump rally outside the White House that turned into a march on the U.S Capitol.

The committee, which recently subpoenaed Trump’s closest aides and advisers for records and depositions by mid-October, is seeking documents and testimony as part of its investigation into the insurrection at the Capitol and Trump’s actions before, during and after the riot, along with Trump’s broader campaign to challenge the election results from inside and outside the federal government.

Trump himself addressed the rally, which was held just south of the White House on the National Mall.

As part of their inquiry, investigators are reviewing ties and communications between Trump White House associates and organizers of the “Stop the Steal” rally, which was planned for the day Congress convened to affirm the election results. Thousands of people traveled to D.C. for the event, with many going on to assault police officers and forcibly enter the U.S. Capitol, temporarily disrupting the electoral count.

Conservative activist Amy Kremer, who founded “Women for America First,” the group that put together the rally supporting Trump on the day of the electoral vote count, was singled out by the panel in their second tranche of subpoenas, along with her daughter, Kylie.

Caroline Wren and Maggie Mulvaney, who were listed on the event permits with the National Park Service, were also subpoenaed, the committee said. Mulvaney is the niece of former Trump chief of staff Mick Mulvaney and worked on Trump’s presidential campaign.

“The Select Committee is investigating the facts, circumstances, and causes of the January 6th attack and issues relating to the peaceful transfer of power, in order to identify and evaluate lessons learned and to recommend to the House and its relevant committees corrective laws, policies, procedures rules, or regulations,” Committee Chairman Bennie Thompson wrote in the letter to each subpoena recipient. “The inquiry includes examination of how various individuals and entities coordinated their activities leading up to the events of January 6, 2021.”

The panel also subpoenaed Hannah Salem, a GOP operative who was listed on the paperwork and previously served as a senior Trump White House press aide.

Katrina Pierson, a former Trump campaign adviser and Tea Party activist who served as a campaign spokesperson in 2016 and spoke at the Jan. 6 rally was also subpoenaed by the committee.

“Americans will stand up for themselves and protect their rights, and they will demand that the politicians that we elect will uphold those rights, or we will go after them,” Pierson said at the rally.

The others subpoenaed were Cynthia Chafian, who submitted the first permit application for the event, and Justin Caporale, Tim Unes, Megan Powers and Lyndon Brentnall, all of whom were listed on permit paperwork.

The committee said Wednesday it had notified the recipients of the subpoenas within the past 24 hours.

Thompson told reporters last week that the committee could also issue subpoenas to former President Trump’s children as part of its investigation. Trump’s two eldest sons, Donald Jr., and Eric, spoke at the rally, as did his daughter-in-law Lara Trump, and Don Jr.’s girlfriend Kimberly Guilfoyle, a former Fox News host and Trump campaign adviser.

(WASHINGTON) — A possible government shutdown is looming as funding runs out at the end of the day Thursday, and Congress has yet to pass a temporary measure to keep the government going.

If one passes both the Senate and House it could be on President Joe Biden’s desk for his signature by Thursday.

But if Congress fails to act, a government shutdown could begin as early as Friday.

If there’s a government shutdown, does everything close?

No, not everything. A full government shutdown would mean federal agencies close their doors or reduce their operations to only what is deemed essential. Programs and agencies that receive mandatory funding or are self-sufficient, such as the U.S. Postal Service, will continue to operate. Only those programs and agencies that are dependent on annual appropriations will be running with empty pockets.

Essential services necessary for public safety such as air traffic control and law enforcement will keep operating — though not necessarily at the same levels.

If essential services continue, why should I care?

During a shutdown, agencies are stripped to the bone, providing only what is necessary to protect life and property or what is required by law. Agency services most directly connected to the public are likely to cease or be severely delayed, seeing “tremendous disruption and uncertainty” as they adjust to reduced staff and operations, according to David Reich of the nonpartisan Center on Budget and Policy Priorities.

National parks and Smithsonian museums will close, and while people will still receive their Social Security payments, benefit verification, processing overpayments and issuing replacement Medicare cards will stop.

There could be delays in air travel with reductions in the Transportation Security Administration’s workforce. If you have any questions about your taxes, there won’t be anyone on the other end of the line at the Internal Revenue Service because it will not be continuing its customer service.

Will the CDC and FDA close – even though we’re in a pandemic?

No, but there might be delays. Among those agencies that typically see a reduction in operations are the Centers for Disease Control and Prevention, the Food and Drug Administration and the National Institutes of Health. While these agencies are integral to coronavirus vaccine distribution and combating the coronavirus, they will be continuing their pandemic-related functions at a much-reduced capacity.

The Department of Health and Human Services, the umbrella agency over the CDC, FDA and NIH, will be furloughing 43% of its employees, according to its shutdown contingency plan. Agencies are responsible for creating their own plans for how they will continue operating if money runs out.

Do we know for sure what services will stop?

Yes, and no. Last week, the White House budget office, the Office of Budget and Management, reminded senior agency officials to review and update their shutdown plans. Some agencies have released their plans outlining what is expected to continue and what will be put on hold.

But according to Maya MacGuineas, the president of the nonpartisan think tank Committee for a Responsible Federal Budget, it’s never clear until a shutdown which services will pass the absolutely necessary test.

“But one thing is for sure, a lot of people will go home and won’t be doing their jobs and that slows down the process of just about everything,” she said.

How many workers will be affected?

There are about 2.1 million civilian federal employees, according to the Congressional Research Service. During a shutdown, federal employees are either sent home or asked to work without pay.

For example, the Department of Defense is planning to reduce its civilian workforce by 55%, and the Environmental Protection Agency will be furloughing 99% of its employees.

For a small fraction of federal employees, their salaries are financed through funding other than appropriations.

Yet for the majority of the federal workforce, the essential employees left staffing agencies would be missing out on their paychecks.

Jacqueline Simon, public policy director of the American Federation of Government Employees, the largest union representing over 700,000 government workers, said that for many federal employees, the lack of a paycheck creates tremendous hardship.

“They have rent to pay. They have mortgages to pay, insurance payments, car payments, child support,” she said. “There is a myth that federal employees are all well paid professionals and that’s just not true.”

About a third of the employees the union represents fall into the category of people who make less than $40,000 a year and may not have the financial cushion to keep working without pay, Simon said.

Federal employees working through the shutdown get back pay, but that will not help them in the interim.

Will a shutdown affect the economy?

A government shutdown does not usually have widespread impacts on the economy unless they drone on for weeks. The 2018-2019 partial shutdown under the Trump administration resulted in economic losses of $1.2 billion each week; it was the longest in the nation’s history, lasting 35 days.

The longer a shutdown lasts, the more areas with high numbers of federal employees could see their local economies begin to suffer because those employees are not getting paid, according to Richard Kogan of the Center on Budget and Policy Priorities.

Government shutdowns create distrust with how the government functions and the uncertainty can impact the economy, MacGuineas said. Compounding the uncertainty is whether Congress is going to pass a raise or suspension to the debt ceiling so the U.S. does not default on its obligations, which is a separate and much more serious issue from the shutdown.
