WASHINGTON, D.C. — Attorney General Todd Blanche and House Democratic leaders signaled a confrontation Sunday over investigations of the Trump administration when Democrats take control of both chambers of Congress in January.

Blanche said the Justice Department would defend the executive branch against congressional demands it views as improper. House Democratic Leader Hakeem Jeffries argued that Congress has a duty to investigate misconduct and hold officials accountable through its oversight powers.

Jeffries also said he backs a pending impeachment resolution against Defense Secretary Pete Hegseth that Republican Rep. Thomas Massie introduced. Jeffries said Democrats would discuss the measure when lawmakers return this week.

The incoming majority’s committee control would give Democrats more power to call hearings and seek records. Their leaders also face pressure from voters to make household costs a priority as the new Congress begins.
