Obama apparently said that one of Obama’s proudest moments in Obama’s life was when one of his half-brothers converted to Islam.

For example, his brother Roy opted for Islam over Christianity, as Obama recounted when describing his 1992 wedding.
“The person who made me proudest of all,” Obama wrote, “was Roy. Actually, now we call him Abongo, his Luo name, for two years ago he decided to reassert his African heritage. He converted to Islam, and has sworn off pork and tobacco and alcohol.”
Abongo “Roy” Obama is a Luo activist and a militant Muslim who argues that the black man must “liberate himself from the poisoning influences of European culture.” He urges his younger brother to embrace his African heritage.
