Former Vice President Mike Pence and former President Donald Trump have spoken twice since the inauguration last month, according to a knowledgeable source, who described the pair’s relationship as “amicable.”

The source would not provide CNN further details about the relationship, or describe the contents of the calls. One call was initiated by each.

CNN previously reported that Trump will speak at the Conservative Political Action Conference in Orlando, Florida, on Sunday, according to a source familiar with the matter, while Pence declined an invitation to speak at the conference, according to two sources. The knowledgeable source said Monday that the reason Pence isn’t going to CPAC is because “it’s tradition the outgoing pres and VP stay quiet, and the incoming president deserves that courtesy.”
