In a recent social media post, President-Elect Donald Trump announced that Katie Miller will be joining the 'Department of Efficiency' in the American government. Katie Miller is known for her role as the press secretary of Vice President Mike Pence and is the wife of Stephen Miller, Trump's newly appointed national security advisor.

According to reports, Katie's appointment is part of Trump's efforts to streamline and optimize government operations. Her background as a communications expert and her experience working in the White House will likely prove valuable in her new role.

Details of Katie's responsibilities and duties in the Department of Efficiency are still unclear, but her appointment is seen as a significant move by the incoming administration to shake up the government bureaucracy and make it more efficient and effective.
