Elon Musk and President Donald Trump's newly promoted White House chief of staff, Stephen Miller, will likely be targets of congressional investigations when Democrats take control of Congress in January, a senior lawmaker said on Sunday, 8 November 2026. California Representative Robert Garcia, who is in line to chair the House Oversight Committee next year, told CNN that the probes will focus on Mr. Musk's role in the Department of Government Efficiency's firing of federal workers last year and on Mr. Miller's role in the immigration crackdown. House Democratic leader Hakeem Jeffries, who will become speaker in January, said separately that Democrats would back a measure to impeach Defense Secretary Pete Hegseth.
The argument that oversight is justified begins with the scale of the election result. Voters delivered a historic rebuke to Republicans in the midterms on Tuesday, 3 November, and the Democrats' sweeping victory gives them the power to chair the committees that investigate the executive branch. Mr. Garcia said there is "a lot of interest, not just from our committee, but from committees across the Congress" in speaking to Mr. Musk, and described Mr. Miller as the architect of a "horrific, unjust" immigration policy who, in his new role, is "at the centre of the major policy decisions" and so deserves scrutiny. Public opinion supports the focus on immigration. A Reuters/Ipsos poll in October found that only 37 percent approved of Mr. Trump's handling of immigration, down from 50 percent when he took office, and the crackdown included operations in which two people were fatally shot in Minnesota by federal agents. Mr. Jeffries pointed to Mr. Hegseth's oversight of the Iran war launched in February, which has led to a spike in gas prices.
The counter-argument is that the administration will not retreat and that the investigations may deepen the divide rather than deliver answers. Attorney General Todd Blanche said that threats by some Democrats to target administration officials and allies were "not something we can tolerate in this country," and added: "If that's what this new incoming leadership wants to do, we are ready. If you work in this administration, you have a lawyer. It's me." Officials and experts who spoke to Reuters expect the administration to continue its aggressive approach to immigration enforcement, amplify cultural conflicts and give no ground to a Democratic-controlled Congress, and the promotion of Mr. Miller to chief of staff on Friday points the same way. The poll that shows disapproval of the immigration policy also shows that 37 percent still approve, a sizeable base, and Democrats will not hold their committee gavels until January, so the current Congress remains under Republican control for now.
The consequences reach beyond Washington. A divided government will shape how the United States handles the Iran war, immigration and its relations with allies, and foreign governments will be watching whether the administration changes course or digs in. Investigations and impeachment threats can also consume the political calendar and limit what Congress achieves on other issues, from budgets to trade.
Democrats have signalled that oversight will be their central tool, and the administration has signalled it will fight. The two months before the new Congress takes office will show how sharp the confrontation becomes.
