There are many reasons to call this article grabage. IMHO, chief among these is the last of sources. Quotes from the article:
They said that Trump also... Neither Lewandowski nor Manafort responded to requests for comment... Lewandowski’s allies... They grumble that... said one campaign operative... the operative said... said one Manafort ally working closely with the campaign... But campaign insiders say it has... said an operative close to Trump... multiple sources said Trump was bothered... said a Washington operative...The operative pointed out that... the operative said... Multiple sources said that Trump... said one operative close to the campaign.
You can publish anything with any slant you want as long as you don’t name sources. And, AFAICT, there are no named sources in this story.
‘last’ in the second sentence should be ‘lack.’
