Aaron Navarro has this story for CBS News. From the article:

Campaign finance experts called the move “unprecedented” and had mixed reactions on if it violated FEC regulations.The transfer of “hard” campaign dollars — money raised under federal fundraising limits — from a super PAC to a campaign has not ever been tried, largely because different laws govern the two types of fundraising entities.

But in this case, Paul Seamus Ryan, a campaign finance expert, told CBS News that Never Back Down is “seemingly circumventing” a prohibition on super PACs directly transferring donations to the campaign, by using the separate draft committee PAC.

“Any way you slice it, this is an unprecedented fundraising tactic,” he said.
