But before he sat down for that interview, we asked Lawrence to give his best elevator pitch — literally, in our building's elevators — to voters on why they should send him to Congress.
We're asking all of the candidates who stop by our offices for these forums to participate. Here's Gov. Maggie Hassan's pitch from a few weeks ago, and you can also look back on elevator pitches from the presidential primary with John Kasich, Bernie Sanders, Martin O'Malley, Carly Fiorina and Hillary Clinton.
Watch the video below to hear Lawrence's pitch. To listen to his full conversation with The Exchange, go here. Or, if you're interested, you can watch a video of the forum taped live in our studios.
Stay tuned for more of NHPR's Conversations with the Candidates (and more elevator pitches) leading up to Nov. 8.
