Who Hillary Clinton and Donald Trump Invited to the First Presidential Debate

The candidates invited a range of supporters to attend the debate tonight.

— -- While the biggest attraction during the presidential debate tonight will be the two candidates on stage, at least some attention will likely be paid to those in the audience.

Here's a look at who the candidates invited to sit in the audience at tonight's debate.

Hillary Clinton

The four women on the list are all supporters who have developed a special relationship with Clinton over the years. They include a 9/11 survivor; a single mom and domestic abuse survivor; and a woman who became a pen pal to Clinton when she was the first lady.

Chelsea Clinton is also expected to attend, according to a spokeswoman for the former first daughter.

And, the Clinton camp said this morning it is hosting 1,200 debate-watch parties across all 50 states tonight.

Donald Trump

This morning, reports emerged that the Republican nominee invited Mark Geist, one of the survivors of the attack on the U.S. Consulate in Benghazi, Libya, to attend the debate.

Geist has been vocal in his support of Trump's candidacy; he spoke on the first night of the Republican National Convention alongside fellow security contractor John Tiegen about the attack in Benghazi.

Trump also over the weekend fired off a tweet about a possible guest to the debate. After Mark Cuban posted about his plans to attend the event in support of Clinton, Trump tweeted Saturday: “If dopey Mark Cuban of failed Benefactor fame wants to sit in the front row, perhaps I will put Gennifer Flowers right alongside of him!”

Bill Clinton admitted in the 1990s to having had a sexual relationship with Flowers two decades earlier.

On Sunday morning, Trump campaign manager Kellyanne Conway told ABC's "This Week" that Flowers, "has not been invited by the campaign."

However, the Clinton camp used Trump's tweet to accuse the Republican nominee of acting unpresidential.
