Newt Gingrich Hit With Grave Charge

" The main point of the piece was actually that Gingrich appeared to be hoarding much of the money raised for his PAC instead of paying it out to fund candidates. But among the people it had given donations to were Sens. Rand Paul and Ted Cruz.

This caught the attention of Media Matters:

After the donations were made, Gingrich hosted Paul on the first episode of Crossfire's revival -- and discussed Cruz on [Tuesday's] episode -- without disclosing his PAC's donations in either instance."
