WASHINGTON (AP) – The House committee investigating the Jan. 6 Capitol insurrection will hear from former Justice Department officials who faced down a relentless pressure campaign from then-President Donald Trump over the 2020 election results.

The officials are also expected to testify about a bizarre challenge from within their own ranks.

Thursday’s hearing will bring focus to a memorably turbulent stretch at the department as the Republican president sought to bend to his will a law enforcement agency that has long cherished its independence.

The testimony aims to show how Trump tried to leverage the authorities of federal executive branch agencies in pursuing his false claims of election fraud.
