Sen. McCaskill Spoke to Clinton After Endorsing a 2016 White House Run

Details of the conversation left wanting

Sen. Claire McCaskill on Thursday said she spoke with Hillary Clinton after endorsing her for president earlier this week but wouldn't reveal details of the conversation.

"She did call me after this all happened the other day; we had a great conversation," McCaskill (D-Mo.) said on MSNBC's "Morning Joe." "I'm not going to talk about what we said but I think she's got a big decision to make and I think she's in the process of making it, and I think the more people that are out there urging her to run, I think it will help grow the grass-roots effort."
