Chris Hayes reacts to Pete Hegseth's hearing and explains why the GOP, despite railing against DEI, is stacking the Trump administration with unqualified picks

A GOP senator who controversially defended President-elect Donald Trump’s pick to lead the Pentagon against allegations of excessive drinking by claiming U.S. lawmakers turn up to vote drunk is sticking to his guns.

Sen. Joni Ernst of Iowa, who had been seen as a key Republican skeptic of Pete Hegseth’s nomination to lead the Defense Department, said she will support him after his performance at Tuesday’s confirmation hearing.
