Maryland Gov.-elect Larry Hogan is expected to pick a transportation secretary from out of state and name one of his Republican primary rivals as secretary of planning, according to several people familiar with the picks.

Hogan (R) will soon name Pete Rahn, who has held transportation posts in New Mexico and Missouri, as Maryland’s next transportation secretary, those familiar with the picks said. Hogan will name David R. Craig, the former Harford County executive, as planning secretary, they said.

The people spoke on the condition of anonymity to discuss about appointments they are not authorized to announce.

Hogan, who takes office Jan. 21, was scheduled to hold a news conference at noon Tuesday to announce his latest Cabinet picks. The event was postponed due to the snowy weather.

Hogan spokeswoman Erin Montgomery declined on Tuesday afternoon to confirm the choices of Rahn and Craig. She said Tuesday’s news conference has not yet been rescheduled.

Maryland’s transportation department oversees both the state’s network of roads and mass transit operations. The department of planning is tasked with guiding the state’s growth.

Rahn is currently a transportation commissioner in New Mexico. He was director of the Missouri Department of Transportation from 2004 to 2010. Prior to that, he served as secretary of the New Mexico Highway and Transportation Department.

Craig, who served as Harford County executive until last month, finished second to Hogan in the June Republican primary for governor. Craig has previously served in the legislature and as mayor of Havre de Grace.
