follow up on

The Makin Review raised questions about the police’s overall handling of the reports it had received in this period and the failure to follow up on them.

A couple of weeks later the fake Hong Kong investment company received an email - Socar wanted to follow up on the lead.

At the same time, she said, a flood of import records to follow up on could overwhelm the department, which is understaffed as it is.

The White House, the report says, “exercised total control over the scope of the investigation, preventing the FBI from interviewing relevant witnesses and following up on tips.”

The U.S. government has a responsibility to follow up on every lead, and respond to every overture.
