Summary

Republican Senator Thom Tillis said White House adviser Stephen Miller “should go” and described him as a “big problem” in the Trump administration. Tillis said Miller exerts “outsized influence” over cabinet operations, constraining cabinet members’ independence and shaping administration actions. The practical consequence is further concentration of operational control in an unelected adviser during a high-stakes immigration crackdown and related federal law-enforcement controversy.

Reality Check

When operational control shifts from Senate-confirmed officials to unelected advisers, our system loses a core accountability channel: public, confirmable responsibility for federal actions. Normalizing “outsized influence” behind closed doors weakens cabinet independence and blurs who can be held to account for enforcement decisions and cross-government directives. That precedent concentrates executive power in roles designed to advise, not govern, eroding democratic guardrails that rely on transparent authority and answerable decision-makers.

Detail

<p>On CNN’s <strong>State of the Union</strong>, Republican Senator Thom Tillis of North Carolina said he believes White House adviser Stephen Miller “should go,” calling Miller’s role in the Trump administration a “big problem.” In response to host Jake Tapper, Tillis said Miller is “more worried about form” than substance and has an “outsized influence over the operations of the cabinet,” which Tillis said results in qualified cabinet members doing less “because of his direction.”</p><p>Tillis said he was the first Republican to call for the resignation or firing of Department of Homeland Security Secretary Kristi Noem and affirmed support for Markwayne Mullin as a replacement, arguing Mullin would be independent of Miller’s influence. Tillis said Miller “calling the shots” gave him pause and asserted Miller drove positions including “we should go after Greenland,” and that Miller has been “repeatedly responsible for embarrassments” by acting too quickly.</p><p>Separately, House minority leader Hakeem Jeffries said a leadership change would not reopen the government to resume funding DHS, calling for policy changes and criticizing ICE conduct.</p>
