Get the deal done.
"The deal makes a lot of sense," he said. "Let's get them to say yes."
Griffin has skin in the game on this one. Citadel, the multi-billion dollar investment firm that he runs, owns stakes in both companies.
Speaking at the CNBC Institutional Investor Delivering Alpha conference in New York, Griffin extolled the idea of a merger with the two media conglomerates on the basis that they would benefit by bringing great content under one roof.
Time Warner, the parent company of CNN and CNNMoney, rejected the bid, but Griffin thinks the fight is far from over.
Many analysts believe Rupert Murdoch will continue to aggressively push for the acquisition. So does Griffin. He believes that Time Warner makes sense as an addition to Murdoch's increasingly global media portfolio.
If Murdoch ups his offer, Griffin thinks it's "going to get tough" for Time Warner's board to say no again.
But Griffin said Time Warner shareholders will have the final word. That's because Time Warner doesn't have a controlling investor like Fox does with the Murdoch family.
"It will come down to every single shareholder vote," he said.
Rupert Murdoch has bought and sold more companies than anyone can remember on his way to building a vast media empire. But not all of those companies have stood the test of time.
Murdoch sent shockwaves through the entertainment industry Wednesday after 21st Century Fox (FOXA) disclosed that it had offered to buy Time Warner for the premium price of $85 billion.
