BuzzFeed is reporting that CNN political analyst and former Donald Trump campaign manager Corey Lewandowski “has been pitching his own super PAC to donors after trashing other groups working on behalf of the GOP presidential nominee, six sources with knowledge of those conversations told BuzzFeed News.”

Lewandowski responded to BuzzFeed by claiming, “‘I have nothing to do with any Superpacs.’ He also denied talking to donors about a potential group.”

The publication added that “Donors have so far been mostly skeptical of his pitch, the sources said, especially since he suggested on CNN that Manafort should resign following Melania Trump’s plagiarized convention speech. There are also concerns about what his contract with CNN would allow him to do -- issues those involved with competing super PACs are stressing as they respond to donors who have been approached.”

CNN has received widespread criticism over its hiring of Lewandowski, who joined the network’s staff days after leaving the Trump campaign. Observers have raised questions over whether Lewandowski signed a non-disparagement agreement with the Trump campaign, and called out the network for hiring someone with a well-reported history of hostile and inappropriate behavior toward reporters.

Earlier this month, CNN disclosed that Lewandowski was still receiving severance payments from the Trump campaign while serving as a CNN analyst, which prompted another round of criticism.
