Washington, Oct 7 (AP) President Donald Trump's administration is warning Tuesday of no guaranteed back pay for federal workers during a government shutdown, reversing what has been longstanding policy for some 750,000 furloughed employees, according to a memo being circulated by the White House.

Trump signed legislation into law after the longest government shutdown in 2019 that ensures federal workers receive back pay during any federal funding lapse. But in the new memo, his Office of Management and Budget says back pay must be provided by Congress, if it chooses to do so, as part of any bill to fund government.

The move by the Republican administration was widely seen as a strongarm tactic — a way to pressure lawmakers to reopen government, now in the seventh day of a federal shutdown.

“That should turn up the urgency and the necessity of the Democrats doing the right thing here,” said House Speaker Mike Johnson at a press conference at the Capitol.

Johnson, a lawyer, said he hadn't fully read the memo but “there are some legal analysts who are saying” that it may not be necessary or appropriate to repay the federal workers.

Democratic Sen. Patty Murray of Washington blasted the Trump administration as defying the law.

“Another baseless attempt to try and scare & intimidate workers by an administration run by crooks and cowards," said Murray, who is the ranking lawmaker on the Senate Appropriations Committee.

“The letter of the law is as plain as can be — federal workers, including furloughed workers, are entitled to their backpay following a shutdown.” Refusing retroactive pay to the workers, some of whom must remain on the job as essential employees, would be a stark departure from norms and practices, and almost certainly would be met with legal action.

While federal workers — as well as service members of the military — have often missed paychecks during past shutdowns, they are most always reimbursed once government reopens.

In a single-page memo from Trump's Office of Management and Budget under Russ Vought, first reported by Axios, the office's general counsel seeks to lay out a legal rationale for no backpay of federal workers.

The memo explains that while the Government Employee Fair Treatment Act of 2019 says workers shall be paid after federal funding is restored, it argues the action is not self-executing. Instead, the memo says, repaying the federal workers would have to be part of legislation to reopen the government.

The OMB analysis draws on language familiar to budget experts by suggesting that the 2019 bill created an authorisation to pay the federal workers, but not the actual appropriation.

Congress, it says, is able to decide whether it wants to pay the workers or not.

For now, Congress remains at a standstill, with neither side — nor the White House — appearing willing to budge. Democrats are fighting for health care funds to prevent a lapse in federal subsidies that threaten to send insurance rates skyrocketing. Republicans say the issue can be dealt with later. (AP) GSP
