The first Republican presidential primary debate of the 2024 election cycle will take place Wednesday night.

The debate will exclusively air on Fox News from 9-11 p.m. ET and will be co-moderated by Fox News anchors Bret Baier and Martha MacCallum.

Former president Donald Trump has announced he will be absent from the debate citing a big lead in polls.

While we can expect eight GOP candidates to gather at Fiserv Forum in Milwaukee to pitch their visions for the country, it's uncertain what iconic moments could come out of Wednesday's broadcast.

From a fly seated on a former vice president's head to a former president looking at his watch, here are some iconic photos from previous debates.
