These letters came out in response to the alleged dodge measures – which is not a government department, but a team within the administration.
The team has been given the task of reducing the rules and federal government costs altogether.
US media reports that the Trump administration has provided access to the federal payment system to Musk’s deputies, which controls the flow of dollars in government funds every year.
As a result, people have criticized the decision online, and the names of the Dodge staff have been publicly divided.
But the action taken by the Reddate was not fully related to Musk’s comments.
On Monday, a prosecutor appointed by Trump said the FBI was investigating the “targeting” of staff.
“Our preliminary overview of the evidence presented to us indicates that some individuals and/or groups have committed law violations in targeting Dodge employees.”
In a letter to Musk, he posted on the X, Mr Martin said he would not tolerate threats against workers or the breaking of the law by angry people.
He wrote, “Any threats, confrontations or other actions that affect their work can break many laws.”
“We will pursue any and all legal action against each one that hinders your work or threatens your people.”
