Assembly Democratic Majority Leader William Horne told The Associated Press on Sunday that he and Assembly Democratic Speaker Marilyn Kirkpatrick were assigned security protection as a precaution because of the threat.
The Las Vegas Review-Journal reported the threat was directed at Kirkpatrick, who didn't respond to messages seeking comment.
The Legislature convenes Feb. 4. Horne declined to comment on published reports that Brooks was upset because of committee assignments Kirkpatrick gave him.
Brooks, a father of four, works as a city of Las Vegas management analyst in the Parks, Recreation and Neighborhood Services Department. He was elected to a second Assembly term in November. He has served on the boards of several organizations, including the Las Vegas Urban League, Hispanic Museum of Nevada and Community Land Trust.
City spokesman David Riggleman said Monday that city administrators will review Brooks' arrest as a personnel matter.
