Anonymous FBI agents say the partial government shutdown is preventing them from effectively doing their jobs and impeding some ongoing investigations.

In a report released by the FBI Agents Association Tuesday, unnamed agents speak about how lack of funding due to the shutdown has hindered their work. One agent said the shutdown has "eliminated any ability to operate" and that "the fear is our enemies know they can run freely," while another said they can't "protect and serve the American people" unless the government is "re-opened immediately," Politico reports

Due to issues with funding, some interviews, indictments, and grand jury subpoenas have been delayed, the report details. The report says that the FBI's agents, currently working without pay, are operating with "increasingly limited resources" and that "this situation is not sustainable."

The president of the FBI Agents Association, Tom O'Connor, shared a similar perspective upon the release of the report. "The failure to fund the FBI is making it more difficult for us to do our jobs," he said, per CBS News, "to protect the people of our country from criminals and terrorists."

There is currently no end in sight to the partial government shutdown, which has entered its 32nd day. President Trump is continuing to insist on $5.7 billion in border wall funding, a request that Democrats have consistently refused, and he signaled on Twitter Tuesday he's not backing down, writing, "No cave!"
