A climate change conference being held in Morocco on Monday comes amid a contentious U.S. election in which Democratic nominee Hillary Clinton faces thorny questions over the millions of dollars she received from foreign donors, including King Mohammed VI of Morocco, in a deal recently disclosed by the group WikiLeaks.

The group has been publishing illegally obtained emails from Clinton campaign chairman John Podesta for the last month. New emails disclosed late last month show deliberations among campaign manager Robby Mook, Podesta and deputy campaign chairwoman Huma Abedin over whether Clinton should go to Morocco in 2015 to talk at a Clinton Global Initiative conference focused on climate change and other issues facing Africa and the Middle East.
