Today marks President Obama’s last full day in office. On Friday at noon, Supreme Court Chief Justice John Roberts will swear in Donald Trump as the country’s 45th president. On Wednesday, Obama gave his last press conference as president, during which he warned Trump that he will not stay silent if he sees what he called the nation’s core values at risk. Obama also thanked the press and spoke about the role they’ve played during his presidency.

President Barack Obama: “Having you in this building has made this place work better. It keeps us honest. It makes us work harder. You have—it made us think about how we are doing what we do and whether or not we’re able to deliver on what’s been requested by our constituents.”

Donald Trump had proposed moving the press corps out of the White House and instead relocating them in the Old Executive Office Building. He had to back away from the proposal Wednesday, after outrage among members of the press and those concerned about press freedoms.
