Hornick specified to Marshall that hotline workers' schedules were being managed to ensure that desks would be manned throughout the day on Monday even as some workers stepped away from the phones to write their weekly work summaries. However, he noted that workers were somewhat caught off-guard by the response deadline, and that most calls to the hotline are from elderly people on fixed incomes having difficulty accessing the money they depend on to live.

"Needless to say, what’s created this crisis posture is the fact that all of this is being demanded on one day’s notice," Mrshall wrote. "According to the email, all the replies must be submitted no later than 11:59 PM tonight."

Musk's "Department of Government Efficiency," or DOGE (which is not yet an official federal agency authorized by Congress) sent the email on Saturday to the roughly two million federal workers over the weekend through the Office of Personnel Management (OPM), which effectively functions as the federal government's human resources department. TPM reporter Josh Kovensky posted to Bluesky that one unnamed "hill source" said that at least one federal judge also got the OPM email.

Some agencies have taken a different approach to the Musk email, with workers elsewhere being told they didn't have to respond to Musk's demands. And federal workers' unions have made it clear that they will have workers' backs if DOGE attempts to remove them for not complying with the ultimatum.

In an all-caps post to his Truth Social platform on Saturday, President Donald Trump made it clear he not only approves of what Musk is doing, but that he should "GET MORE AGGRESSIVE." He added that "WE HAVE A COUNTRY TO SAVE," though he didn't specify what he was attempted to save the country from.
