The state Senate's sergeant-at-arms announced his retirement today.

Tony Beard Jr. retired after it surfaced he withheld information about one of his employees using cocaine from state Senate Leader Darrell Steinberg.

Beard's resignation marks a 46-year career in the state Senate.

Steinberg issued a statement saying Beard "has served California’s Legislature with great distinction and honor for more than four decades. Throughout his tenure as Chief, he has raised the standards of the Senate Sergeants-at-Arms office and brought more diversity to his staff."

Deputy Chief Sergeant-at-Arms Katrina Rodriguez will become the interim chief until the Senate Rules Committee elects a new chief sergeant-at-arms.
