Trump’s Office of Management and Budget under Russell Vought has moved with more executive authority over spending, which is typically left to Congress. The administration took steps to cancel foreign aid and asserted power to withhold billions of domestic spending.

“I would expect this shutdown to look different than any other shutdown,” said Joshua Sewell, Taxpayers for Common Sense director of research and policy. He said he expects that the Trump team’s actions would be guided by what they believe achieves the most for them politically.

Trump could use a shutdown to dismantle government functions, wrote Max Stier, chief of executive of the Partnership for Public Service, a nonprofit focused on improving the federal government.

If lawmakers can’t reach a deal, Stier wrote, Trump and Vought “will have enormous latitude to determine which services, programs, and employees can be sidelined, decisions that could go far beyond what has occurred during past shutdowns.”
