U.S. House Minority Leader Hakeem Jeffries has backed an expected resolution to impeach Defense Secretary Pete Hegseth, as Democrats prepare to use their incoming congressional majorities to investigate President Donald Trump’s administration, Al Jazeera reports.

“I’m a hard yes on the Hegseth resolution,” Jeffries said Sunday on ABC’s This Week with George Stephanopoulos. He accused Hegseth of abusing his power, undermining national security and engineering a “reckless and costly war of choice in Iran.”

The resolution, expected in the coming days, is being spearheaded by outgoing Republican Representative Thomas Massie of Kentucky, a critic of the U.S.-Israel war on Iran, according to Al Jazeera. Jeffries predicted strong support, but no impeachment vote has been reported.

Democrats won control of both the House and Senate in the Nov. 3 midterm elections. The new Congress will be sworn in Jan. 3, and Jeffries is poised to become House speaker. Republicans retain control of both chambers until the transition.

Jeffries said Democrats would act “aggressively” during their first 100 days to address affordability and what he described as corruption under Trump.

Representative Robert Garcia, who has announced a bid to lead the House Oversight Committee, outlined possible investigations in a separate Sunday appearance on CNN. He said White House chief of staff Stephen Miller’s role in immigration policy warranted scrutiny, citing family separations and allegations of due-process abuses.

Garcia also expressed interest in questioning Elon Musk about the Department of Government Efficiency, including federal workforce cuts and its pursuit of access to sensitive government data. His concern that personal data may have been compromised was not presented as an established finding.

Attorney General Todd Blanche pushed back on CNN, saying the administration was ready to counter Democratic investigations and impeachment efforts. He also raised the possibility of investigations into Democratic lawmakers over what he called threatening rhetoric. Trump similarly called for a Justice Department investigation in a Saturday social-media post.

The House can impeach an administration official by a simple majority. Conviction and removal require a two-thirds Senate vote, a substantially higher threshold even under Democratic control.
