LAS VEGAS, Oct. 19 (UPI) -- The two presidential candidates are bringing symbolic guests to their third and final debate Wednesday night.
Democrat Hillary Clinton has selected two billionaires -- Meg Whitman, the Hewlett-Packard CEO and former Republican California gubernatorial candidate, and Mark Cuban, the owner of the Dallas Mavericks and star of ABC's Shark Tank.
Malik Obama, who is a U.S. citizen, announced he is supporting Trump in July.
"I'm excited to be at the debate. Trump can make America great again," Malik told The New York Post.
"I look very much forward to meeting and being with Malik," Trump also told the newspaper Wednesday. "He gets it far better than his brother." Malik Obama shares the same father with the president but has a different mother.
Smith, whose son Sean was killed along with three others in the attack on the U.S. diplomatic compound in Benghazi in 2012, spoke at the Republican National Convention in Cleveland. She said that Clinton "should be in stripes."
Smith has said Clinton lied to her about what happened in Benghazi after the attacks. Clinton has denied ever giving Smith false information
At the second presidential debate, Trump invited three women who have in the past accused former President Bill Clinton of inappropriate sexual behavior.
Clinton campaign spokeswoman Jennifer Palmieri confirmed to CNN that Whitman and Cuban have agreed to attend the debate.
Cuban, who endorsed Clinton in July, was at the second debate, sitting in the front row as her guest.
"Trump scares me," Cuban said at a July campaign event in Pittsburgh. "Donald, initially, I really hoped he would be something different, that as a businessperson, I thought there was an opportunity there. But then he went off the reservation and went bats -- crazy."
After the debate, Trump called him "dopey."
Clinton often mentions Cuban and billionaire investor Warren Buffett as "real billionaires."
Whitman endorsed Clinton earlier this year and said she would donate to Clinton.
