Donald Trump is bringing President Barack Obama’s Kenyan-born half-brother, Malik, to Wednesday’s third and final presidential debate, a campaign aide confirmed to CNN. Hillary Clinton will be joined at Wednesday’s debate by two well-known billionaires who are backing her campaign, in what may be an attempt to rattle Republican nominee by su btly questioning his own net worth. Meg Whitman, the Hewlett-Packard CEO and former Republican California gubernatorial candidate, and Mark Cuban, the outspoken billionaire owner of the Dallas Mavericks, will both be Clinton’s guests at Wednesday’s third and final presidential debate. Meanwhile, Trump is countering with Obama’s half-brother and a ghost from Clinton’s past: Patricia Smith, the mother of Benghazi victim Sean Smith, who has accused the former secretary of state of “murdering” her son. The New York Post first reported Trump’s invitation to Obama’s half-brother. The Post also reported that Malik Obama called now-deceased Libyan dictator Moammar Gadhafi one of his best friends – a potential source of awkwardness for Smith. Malik Obama, who was born in Kenya and is an American citizen, voiced his support for Trump in July, saying he hoped to meet the Republican nominee. Trump’s feelings are mutual. “I look very much forward to meeting and being with Malik,” Trump said Wednesday. “He gets it far better than his brother.” Malik Obama shares the same father with the president but has a different mother. He told the Post on Wednesday that he blames Clinton, who was secretary of state at the time Gadhafi was toppled and killed, for making the situation worse in Libya. Clinton invited both Cuban and Whitman, campaign spokeswoman Jennifer Palmieri said, and the duo agreed to attend. Obama: Trump’s rigged election claim ‘whining before the game’s even over’ Whitman, a longtime Republican, endorsed Clinton earlier this year, saying in a statement that she would vote for and donate to Clinton. Since then, Whitman has headlined events for Clinton and contributed a considerable amount of money to her campaign, including attending a $50,000-a-person fundraiser in California earlier this year. Cuban sat in the front row at Clinton’s first debate against Trump, a move that was intended to shake the Republican nominee because the Dallas Mavericks owner has been so outspoken against the businessman. Cuban endorsed Clinton at a July event in his native Pittsburgh. Afterwards, he told CNN that Trump was “bats— crazy.” “Trump scares me,” Cuban said after speaking at the event. “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.” Trump lashed out at Cuban for attending the debate with Clinton, calling him “dopey.” Nevada poll: Clinton leads Trump by 7 Since announcing her candidacy, Clinton has picked up a group of high-profile billionaire backers. The campaign has, in turn, used them to question Trump’s wealth, citing the fact that he has not released his taxes as a reason for the questions. Clinton regularly mentions Cuban and billionaire investor Warren Buffett at events across the country, calling them “real billionaires” compared to Trump. ‘She murdered him’ Trump’s campaign did not immediately respond to a request for comment about Clinton’s guests or Smith. At the second presidential debate, Trump appeared with three women who have in the past accused former President Bill Clinton of inappropriate sexual behavior as part of an effort to rattle Hillary Clinton. Trump invited Kathleen Willey, Juanita Broaddrick, Paula Jones and another woman, Kathy Shelton, whose alleged rapist was defended by Clinton as a young lawyer. Smith confirmed to CNN that she will be attending the debate at the Trump campaign’s request. She said she doesn’t know where she’s sitting yet, but she’s “heard rumors” that it’ll be the front row. “I would like to have Hillary tell me what happened,” she told CNN. “I know she murdered him … I do hope she will tell me something. I don’t think she will because I don’t think she’s got the guts to tell me what happened (in Benghazi).” Smith spoke at the Republican National Convention in Cleveland, where she told the audience of Republicans that Clinton “should be in stripes.” “This entire campaign comes down to a single question: If Hillary Clinton can’t give us the truth, why should we give her the presidency?” Smith said to cheers on the convention’s opening night. Her son Sean, a foreign service information management officer, was killed along with US Ambassador to Libya Chris Stevens and two CIA contractors in the 2012 attack on the US diplomatic compound in Benghazi.
