It has been revealed that Donald Trump invited Malik Obama, President Barack Obama's half-brother, to the third and final presidential debate in Las Vegas. ABC News reported that Malik's appearance at the debate [1] will signify an "attack on the sitting president."

So, who is Malik Obama? Malik was born in Nairobi, Kenya, in 1958 — making him three years older than President Obama — to Barack Obama Sr. and his first wife, Kezia [2]. He also goes by Abongo or Roy, however, he is usually referred to as Malik in the press.

Having grown up in different countries, the half-brothers didn't meet until they were adults, when President Obama traveled to Kenya. In his book Dreams of My Father, the president described meeting Malik [3] for the first time: "When I opened the door, I found a big man standing there with his hands in his pockets, an even-toothed grin breaking across his ebony face," adding, "His resemblance to the Old Man was unnerving. Looking at my brother, I felt as if I were ten years old again."

The half-brothers kept in touch and even ended up being the best man at each other's weddings [4]. Malik became a US citizen after residing in Washington DC on and off since 1985. In 2013, Malik ran for governor [5] in the Kenyan county of Siaya, however, he lost by a large margin. He currently works as an independent financial consultant [6].

Malik has stated that he and President Obama have since drifted apart [7]. Obama's biographer revealed at least one possible reason why the two half-brothers have grown distant in a tweet posted on Wednesday.

As Obama biographer, I dealt with many Kenyan relatives. Now Trumpster Malik by far the least reliable, consumed with pub & money.

Earlier this year, Malik announced he would be voting for Donald Trump [9] in the upcoming presidential election and said he admired the candidate for being "straight-forward."

Wow, President Obama's brother, Malik, just announced that he is voting for me. Was probably treated badly by president-like everybody else!

In an interview with Page Six, Malik said he's looking forward to attending the third debate [11]. He said, "I'm excited to be at the debate. Trump can make America great again." He also said he doesn't believe the ongoing sexual assault claims against Trump [12], adding, "Why didn't they come forward before?"

In addition to women who accused Bill Clinton of sexual assault, Trump previously invited Kathy Shelton [13] to the second presidential debate. Shelton is a former legal client of Hillary Clinton who is now speaking out against the Democratic candidate.
