Stephen Miller Top Contender

To replace Mike Waltz as Trump's National Security Advisor.
Tim Waltz abruptly left the position on Thursday. Initially, there was speculation that it was tied to "Signalgate," after it was revealed that Trump administration officials used the Signal app to discuss sensitive military operations and that a journalist was mistakenly added to a private group chat. But Trump then announced he was nominating Waltz to serve as UN Ambassador.
According to Axios, five sources familiar with the situation told the outlet that Miller was likely to get the job — if he wants it. More on that in a bit.
One of the sources (in the White House) told Axios that Miller has made the Homeland Security Council run "like clockwork" and that the organization is "infinitely more effective than the NSC [National Security Council] with a tiny fraction" of previous staff.
The 39-year-old founder of America First Legal, a 501 nonprofit organization that prides itself in "fighting back against lawless executive actions and the radical left," is a fearless defender of the administration's legal push for immediate deportation of illegal aliens without court hearings.
Anyway, Miller, who served as a senior advisor in Trump's first administration, is an intellectual near-robotic beast — I say that as a compliment — who doesn't suffer fools gladly, and would likely be an ideal fit as National Security Advisor. According to one of the sources, per Axios, Miller works well with Secretary of State Marco Rubio.
While one source said Miller suggested he was interested in the job Thursday, another source told Axios that he might not take the job "if it takes him away from his true love: immigration policy."
Not quite "palace intrigue," but given the strong — some would say unprecedented — team put together by Trump, this go-around, it's hard to imagine that things won't work out, one way or another, to everyone's advantage, not only in the Trump administration but for the American people, as well.
