About 5000 attorneys, agents, intelligence analysts, and other professionals are on furlough from the FBI due to the government shutdown, resulting in reduced staffing for critical functions. A spokesman wouldn’t go into detail about which investigations were impacted but said the agency’s mission was impaired. He described a growing backlog at the labs that provide forensic-analysis support services and said that funds supporting drug trafficking and undercover operations have been dangerously limited. If the shutdown doesn’t end soon agents in various field offices may stage a coordinated sick day in protest, but for now, the agents association is simply putting pressure on public officials. In a petition sent to the White House, the vice president’s office, and House and Senate leaders, the association warned of the effects of the ongoing shutdown on the bureau’s work.
