ALISYN CAMEROTA (HOST): David, let's talk about some of the things that have been part of the conversation in the past few days. Donald Trump invoked the, he calls it, “mystery,” surrounding Vince Foster, who was deputy counsel at the White House during Bill Clinton's time, about the death of Vince Foster. That has been investigated time and again by police, by Ken Starr, by CNN. It was a suicide, but Donald Trump acts as though it's an open question. So what now? Should the media go back and sort of remind voters about all of this and about all of the details to try to put it to rest, or is this just -- there are conspiracy theorists out there and Donald Trump has always sort of been sympathetic to those.

DAVID GREGORY: Look, the people who are open to the relitigation of Vince Foster's death are not going to vote for Hillary Clinton anyway. ​​​​So Donald Trump is speaking to conspiracy-minded people who are not based in reality on some on these stories anyhow and maybe they're part of his coalition.
