Trump: "I'm proud to shut down the government" over border wall

Prior to his meeting with Rep. Nancy Pelosi and Sen. Chuck Schumer, President Trump brought reporters into the Oval Office and — in an extended, heated exchange before the cameras — clashed with the two Democratic leaders over congressional support for funding for his border wall, declaring that he is "proud to shut down the government for border security."

Why it matters: The president taking ownership of any potential government shutdown hinders Republicans' ability to pin the blame on Democrats, while also giving a glimpse into what Trump's negotiating style with a Democrat-controlled House may look like over the next two years.
