Let the games begin. The guest lists for the presidential candidates for Wednesday night's final debate in Las Vegas have turned into a form of psychological warfare.
Republican nominee Donald Trump is bringing President Barack Obama's half-brother Malik Obama.
"I look very much forward to meeting and being with Malik," Trump told Page Six. "He gets it far better than his brother."
Malik Obama, who was born in Kenya and came to the United States as a young boy, is reportedly registered to vote in Maryland, according to the New York Post.
He told the paper in July that he supports Trump because he believes his brother and then-Secretary of State Hillary Clinton made a mistake by intervening in Libya in 2011.
"I still feel that getting rid of [Libyan dictator Muammar] Gaddafi didn't make things any better in Libya," he said. "My brother and the secretary of state disappointed me in that regard."
Trump is also bringing another prominent figure in the Libya intervention: Patricia Smith, the mother of Sean Smith, a U.S. diplomat who was killed in the attack on Benghazi on Sept. 11, 2012.
This isn't the first time Trump has tried to rattle Clinton by placing controversial guests in the audience at a debate. During the second debate on Oct. 9 in St. Louis, Trump invited several women who have accused Clinton's husband, former President Bill Clinton, of sexual assault. He also invited Kathy Shelton, whose alleged rapist Hillary Clinton represented in court 40 years ago.
Clinton is inviting two high-profile guests of her own to the third and final debate. Hewlett-Packard CEO Meg Whitman, a longtime Republican who is now backing the Democratic nominee, and Mark Cuban, the billionaire owner of the Dallas Mavericks, will attend, according to CNN.
Cuban has been very outspoken in his dislike for Trump.
On Wednesday afternoon, NBC's Katy Tur reported that Trump is bringing several other guests to the debate, including the fiance of U.S. Ambassador Chris Stevens, who was killed in Benghazi in 2012 and Marcus Luttrell, retired Navy Seal and co-author of Lone Survivor.
On Wednesday afternoon, the Clinton campaign announced several more guests for the debate.
Clinton has invited two women from Nevada, Karla Ortiz, a young girl born in Nevada to undocumented parents, and Astrid Silva, an activist for immigrants.
And she invited Ryan Moore, who she met as a young boy in 1994, to help highlight her healthcare policy.
She also invited Ana Scott, the mother of a soldier killed in Iraq in 2007 while awaiting citizenship and Gary Crane, who was her son's teacher.
