He is expected to enter a plea to a three-count indictment charging him with conspiracy and possession with intent to distribute 5 kilograms or more of cocaine in the Billings area from March 2006 until September.
Henry, 30, was arrested along with a co-defendant, James Mack, during an undercover drug deal on Sept. 30 in the Denver area.
Mack, 29, is set to appear in Billings next Friday.
Henry and Mack are suspected of supplying large amounts of cocaine to Billings customers. The men were arrested after Montana law enforcement officers stopped a vehicle near Billings and found cocaine and marijuana inside. A passenger, who told officers the drugs came from Henry, cooperated and helped set up the undercover drug deal that led to the arrest of Henry and Mack.
A magistrate judge in Colorado set Henry's bail at $400,000, which he posted with $40,000 and a $360,000 secured bond on his Aurora, Colo., house.
Mack was released from jail in Denver on Friday on a $10,000 bond.
While on release, Henry and Mack are required to be on electronic monitoring.
