Malik Obama, who attended the presidential debate as a guest of Donald Trump, says he is “disappointed” in his half-brother, President Obama.

“Before he was running for office, he was everybody’s friend,” the Kenyan-born Obama said on Fox News Channel’s “Hannity” on Wednesday. “Since he’s become the president, he’s changed. I can’t reach him.”

Malik Obama told Sean Hannity he is disappointed in his half-brother for being changed by the office and “mesmerized by the power” of being president. He noted that his former humility and willingness to listen have given way to being “too formal and stiff.” He added that he would like to have dinner with his brother but is never able to meet with him for more than 15 to 20 minutes.

“I thought maybe we could be a family,” he said, contrasting their relationship with that of President John F. Kennedy and his brother Robert. “I would have thought that it would have been different.”

Malik has thrown his full support behind Trump and said the GOP nominee has a track record of building successful businesses into his current business empire. “I don’t see why he can’t do that for the country,” he said.

“Another thing,” he added. “The Republican Party is the party of Lincoln. Lincoln freed the slaves.”

He also credited former President George W. Bush for opening an immigration case for his aunt, which he says he really appreciated.
