Your link is June 13th. That story cites an NPR interview on the 12th. And again Newsmax is Ruddy.
No, my link does not say the story was first published on the 13th. It says it was last UPDATED on the 13th:
‘CBS NEWS
Last Updated Jun 13, 2017 8:59 PM EDT’
Here is the quote that clarifies the source:
‘The interview was first mentioned by Trump friend and Newsmax CEO Chris Ruddy in an interview on PBS’ “NewsHour” Monday evening.’

If you post to me again, please answer the following two questions.
A: Who were NPR’s two sources?
B: How do you know the Monday interview was NPR’s first mention of the Ruddy info? I.e.: something led to NPR’s interview of Ruddy. NPR wouldn’t interview a conservative friend of Trump’s just for the pleasure. In some venue NPR most likely got the info from Ruddy and released it, and then followed up with an interview.
