"The Democrats are dealing with a new reality in how this new president will communicate, the tweets," PBS NewsHour's Judy Woodruff reminded Vice President Joe Biden in an interview that aired Thursday night. She read two of Trump's tweets, about Senate Minority Leader Chuck Schumer (D-N.Y.) and President Obama, and Biden jumped in. "Grow up, Donald, grow up," he said. "Time to be an adult, you're president. You gotta do something. Show us what you have. You're going to propose legislation, we're going to get to debate it, let the public decide, let them vote in Congress, let's see what happened. It's going to be much clearer what he's for and against, and what we're for and against, now that it's going to get down to actually discussing in detail these issues that affect people's lives."
Elsewhere in the interview, Biden summarized what he could about the U.S. intelligence community's report on Russia's interference in the U.S. election, and criticized Trump's spitballing of those conclusions. "For a president not to have confidence in, not to be prepared to listen to, the myriad intelligence agencies, from Defense Intelligence to the CIA, is absolutely mindless," Biden said. "The idea that you may know more than the intelligence community knows — it's like saying I know more about physics than my professor. I didn't read the book, I just know I know more." He also called Trump "a good man." You can watch the entire interview below. Peter Weber
