There was a second Obama presidential endorsement this week.

On Monday, former Democratic President Barack Obama endorsed Joe Biden, the last Democrat standing after a brutal primary season in which some two dozen other hopefuls stepped aside.

Now, his half-brother, the African-born Malik Obama, has endorsed Republican Donald Trump, just as he did in the 2016 race.

"Today I Endorse and Will be Voting for President Donald J. Trump (@realDonaldTrump) in November 2020. #MAGA," he wrote on Twitter

Comments by Twitter users included, "The cooler brother!" and "The lesser-known, but more real Obama."

Malik Obama is Barack Obama's older half-brother. They each served as best man at the other's wedding, but the relationship deteriorated over the years.

In an interview last year with "The Hidden Truth Show with Jim Breslo," Malik said Barack turned his back on him when his family needed help, PJ Media reported.

Malik said the same thing happened when two of Malik's children died while waiting for approval to come to the United States.

"I told him, brother, you've got to help me out," Malik said.

He said that while illegal immigrants claimed a right to be in the U.S., he was "struggling to follow the legal channel."

Malik said the falling out centered on Malik establishing the Barack H. Obama Foundation, named for Barack Obama Sr.

"He said if I don't shut it down, he is going to cut me off," Malik said. "This was an opportunity to do something. If he were to be a part of it, it would not be an issue. It is my father’s foundation."

Malik called his brother "a narcissist."

"He feels like he is only one."

Malik added that Barack Obama Sr. was never a goat herder, as Obama claimed in his book "Dreams from My Father" and in numerous speeches.

Malik was a guest of Trump during a presidential race debate in 2016.

WND reported in April 2015, in the first of a two-part story, Malik's concerns that after Barack Obama made “a very big deal” of his African roots in his autobiographical book and in his first campaign for the White House, he cynically abandoned members of his African family.

During the 2008 campaign, photos of Malik at Barack's wedding were circulated by media.

“Barack’s not been an honest man, as far as I’m concerned, in who he is and what he says and how he treats people,” Malik told WND at that time, noting their relationship was once “very close.”

In the second part, Malik charged that Barack exploited his impoverished African family for political gain then abandoned them after reaching the White House.
