A super PAC supporting former tech executive Carly Fiorina's run reported raising $3.5 million -- with a half-million dollar lift from a super PAC supporting GOP presidential rival Sen. Ted Cruz (R-Tex.).

The pro-Cruz PAC, Keep the Promise I, reported the disbursement Friday in a document filed with the Federal Election Commission. That is...unusual, to say the least.


Cruz has four allied super PACs, all named some variation of “Keep the Promise.” Together they raised an estimated $38 million, according to FEC documents.
