Trump aide’s wife leaves White House to work for Elon Musk hours after he posts intriguing tweet

Katie Miller is following Elon Musk from the White House back to the private sector as the tech billionaire officially leaves his post in Washington, D.C.

But her husband, Stephen Miller, appeared to respond negatively to her boss’s criticism of President Donald Trump’s massive spending bill.

The top Trump aide caused a stir on social media on Tuesday after Musk said he was ‘disappointed’ in the One Big Beautiful Bill Act and claimed it went against the cuts he worked hard to implement during his months at the Department of Government Efficiency.

It seemed that Miller, the Homeland Security advisor and White House deputy chief of staff for policy, reacted to those comments via subtweet later that night.

He explained on X that Congress was not able to cut discretionary spending in the way that Musk’s agency aimed to do.

‘Under senate budget rules, you cannot cut discretionary spending (only mandatory) in a reconciliation bill,’ Miller wrote to social media on Tuesday. ‘So DOGE cuts would have to be done through what is known as a rescissions package or an appropriations bill.’

‘The Big Beautiful Bill is NOT an annual budget bill and does not fund the departments of government,’ he went on. ‘It does not finance our agencies or federal programs.’

Katie Miller served as an adviser and the spokeswoman for DOGE, but will leave the White House to work ‘full time’ for Musk on the private sector side, according to a CNN report.

Her new duties could include booking his media appearances for Tesla and SpaceX, one source confirmed.

In just the past week, Musk has given interviews to the Washington Post, CBS News and Ars Technica about SpaceX’s Starship now failed launch.

While in government, Miller had been considered a Special Government Employee, which allows private sector figures to work for the federal government, but restricts them to 130 days per year.

Musk officially quit his position as the head of DOGE this month and announced Wednesday he was stepping down from his role alongside Trump.

He is now set to dedicate more time to his private sector ventures. 

‘I think I probably did spend a bit too much time on politics,’ Musk told Ars Technica this week when asked about priorities and the failed SpaceX launch. 

He insisted: ‘It’s less than people would think, because the media is going to over-represent any political stuff, because political bones of contention get a lot of traction in the media.’ 

‘It’s not like I left the companies,’ Musk continued. ‘It was just relative time allocation that probably was a little too high on the government side, and I’ve reduced that significantly in recent weeks. 

The richest man on earth was initially scheduled to depart from the administration by May 30, and has spent the last few weeks slowly phasing out of politics amid whispers of tensions with top administration officials.

Musk called Trump’s One Big Beautiful Bill Act a ‘disappointment’ because it ‘undermined’ the work he did at DOGE. The same day, Stephen Miller posted the above tweet to X

The situation came to a head on Tuesday night when Musk laid into Trump’s ‘big beautiful bill’ and admitted he was disappointed with the treatment his DOGE team had received. 

‘It undermines the work that the DOGE team is doing,’ Musk bluntly told CBS of the $3.8 trillion tax and spending bill. 

Musk – who spoke to multiple outlets about the White House betrayal – went on to decry the treatment he and his baby-faced DOGE henchmen had received.  

‘DOGE is just becoming the whipping boy for everything,’ he told the Washington Post. 

‘Something bad would happen anywhere, and we would get blamed for it even if we had nothing to do with it.’

After helping Trump win the 2024 election with outrageous financial contributions and stage-jumping endorsements, Musk earned the title of ‘First Buddy’ in the White House.

For the first several months of Trump’s second term, Musk was everywhere – briefing Trump personally, gutting federal departments and even bringing his son, X, along to crucial meetings in the Oval Office.

But his arrival ruffled feathers both within the political establishment and among governmental employees, particularly when he set about mercilessly slashing jobs in an effort to root out wasteful spending. 

‘People burning Teslas,’ he told the Post. ‘Why would you do that?’

Musk had been a vocal presence in the first few months of the Trump administration, even bringing his son X along to the Oval Office for a press conference about DOGE’s activities

As Tesla showrooms around the nation became the epicenters of violent protests, stock prices nosedived and reports emerged that the board was seriously considering replacing Musk. 

‘I think I probably did spend a bit too much time on politics,’ Musk admitted in a separate interview with ARS Technica.

‘It’s not like I left the companies. It was just relative time allocation that probably was a little too high on the government side, and I’ve reduced that significantly in recent weeks.’

Musk twisted the knife a little further with outspoken criticism of Trump’s ‘Big, Beautiful Bill.’ 

‘I think a bill can be big or it can be beautiful, but I don’t know if it can be both,’ he said. ‘My personal opinion.’ 

The bill is estimated to add another $3.8 trillion to the national debt which currently stands at a monstrous $36 trillion. 

‘The federal bureaucracy situation is much worse than I realized,’ he said.

‘I thought there were problems, but it sure is an uphill battle trying to improve things in D.C., to say the least.’

Musk saved an estimated $160billion in what he labeled wasteful government spending by decimating or shutting down 11 federal agencies – putting about 250,000 federal employees out of work in the process.

But even that number is a far cry from the $2trillion he vowed to save when DOGE was launched, and it has cost him immensely with mounting lawsuits and global protests against both he and his companies.

Still, Trump praised Musk as he revealed the billionaire had taken a step back from DOGE and said he would have been welcome to ‘stay as long as you want.’ 

Musk, in turn, praised the president in his own statement.

‘As my scheduled time as a Special Government Employee comes to an end, I would like to thank President Trump for the opportunity to reduce wasteful spending,’ he wrote on X on Wednesday night.

‘The DOGE mission will only strengthen over time as it becomes a way of life throughout the government.’
