Spiker submitted his resignation earlier this month, and a vote on his replacement is scheduled for March 29.
Spiker plans to work for U.S. Sen. Rand Paul's political action committee. Rand Paul is a potential 2016 presidential candidate, and Spiker had previously backed Paul's father, former U.S. Rep. Ron Paul.
