Story highlights Clinton's top aide Huma Abedin described a Moroccan arrangement in a recently leaked email

Abedin wrote that Clinton's "presence" at a conference was a condition for a donation

Fletcher, North Carolina (CNN) Donald Trump on Friday accused his rival Hillary Clinton of engaging in "pay for play" for accepting an invitation to speak at a Clinton Global Initiative event in Morocco in exchange for a $12 million donation pledge to the Clinton Foundation from that country's king.

The accusation is just the latest Trump has leveled against Clinton as he's argued she engaged in "pay for play" schemes involving the Clinton Foundation during her time as secretary of state. But the Clinton Global Initiative summit in Morocco that Clinton was set to attend in exchange for the $12 million pledge took place in May 2015 and was discussed in emails by Clinton's top aides in November 2014, after her tenure as secretary of state ended.

Clinton did not end up attending the summit. CNN has reached out to the Clinton campaign for comment on Trump's comments and have not yet gotten a response.

The accusation is just another example in Trump's attempts to label Clinton as a "corrupt" figure as he increasingly looks to frame his candidacy as that of an outsider looking to shake up the system.
