CALLAHAN COUNTY, Texas -

A half-brother of President Barack Obama is scheduled to speak at a one- day convention put on by Yisrayl Hawkins on Friday.

Hawkins is head of the reclusive religious group House of Yahweh, which has a compound in Callahan County, just east of Abilene.

This isn't the first time that Malik Obama, who shares a father with Barack, has spoken at the compound.  In April of 2013, he also spoke at the one-day Peaceful Solution Character Education Program.

The one-day convention, according to its website, is an effort to improve morality worldwide.
