Elon Musk’s new preferred equity financing for the $44 billion buyout of Twitter (NYSE:) has been put on hold as the uncertainty around the deal grows, according to Reuters.

Earlier this week, Musk’s lawyers sent a letter to Twitter warning the billionaire may abandon the deal if the social media company fails to provide the requested data on bot accounts.

Musk has to contribute $33.5 billion cash and secured debt financing in order to repay the rest. This is because the majority of Musk’s wealth lies in Tesla (NASDAQ:) stock, making his liquidity limited.

In order to decrease his cash contribution towards the Twitter deal, Tesla CEO Elon Musk has been negotiating privately with Apollo Global Management (NYSE:), to obtain additional preferred equity financing between $2 billion and $3 billion. This funding was put on hold due to the uncertainty around the deal.

Suspending the financing activities indicates that Musk’s warnings are impeding the development of the deal, though Twitter has argued that Musk has been responsibly fulfilling his contract obligations.
