David Litt went right out of college to join the Obama's 2008 campaign. His time working for Obama didn't stop there as he became a speechwriter for the president from 2011 to 2016. Litt reflects on this inhis memoir, Thanks, Obama: My Hopey, Changey White House Years. He shares what it was like to come of age in the Obama White House, and discusses how he thinks Obama's legacy and work can survive in the Trump age.  Note: Ilya Marritz guest-hosted this segment of "The Leonard Lopate Show."
