Pastor Kirbyjon Caldwell is expected to arrange a surrender date with a Louisiana judge on Monday, his lawyer, Dan Cogdell, told ABC News. Cogdell said he and Caldwell will then travel to Louisiana to seek a bond agreement from the judge.

The Securities and Exchange Commission last week charged Caldwell and Gregory Allen Smith of Shreveport, La., with multiple counts of fraud over a scheme affecting at least 27 mostly elderly investors from 2013 to 2014.

The two face up to 30 years in prison if convicted, ABC News reported.

Caldwell — pastor of Houston megachurch Windsor Village United Methodist — and Smith allegedly promised investors high returns on bonds issued by the Republic of China before 1949, when communist forces successfully revolted and took control of the government.

Caldwell served as a spiritual adviser to George W. Bush. He introduced Bush as the GOP presidential nominee at the 2000 Republican National Convention, and delivered the opening prayer at his first inauguration.

Caldwell went on to endorse Obama in 2008. He defended Obama's Christian faith while he was subject to conspiracy theories about his true nationality and religion.
