It was a moment worthy of fanfare: the opening of a new district office of the Bureau of Alcohol, Tobacco, Firearms and Explosives in New Jersey last month.
Federal prosecutors, law enforcement officials and members of Congress, including Senator Frank R. Lautenberg, assembled at the federal building in downtown Newark, a city plagued by gun violence.
But soon after Representative Robert E. Andrews arrived, an organizer took him aside, at the urging of Mr. Lautenberg’s assistants, and asked him to leave. He retreated, as his colleagues headed to the microphones.
This is what life has been like for Mr. Andrews since early last month, when he startled the Democratic establishment by mounting a primary challenge against Mr. Lautenberg, the state’s senior senator. Mr. Andrews has waged an aggressive campaign, raising questions about the 84-year-old Mr. Lautenberg’s age and barraging him with tough television advertising.
