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 like what Musk's agency aimed to do.
