President Trump has called for a wall along the border with Mexico to stop undocumented immigrants and drugs from entering the United States. But Border Patrol agents on the front lines say they need more technology and additional personnel to curb the illegal traffic, according to a report released on Thursday by Democrats on the Senate Homeland Security Committee.

The report was based on internal Customs and Border Protection documents from the 2017 fiscal year. It concluded that less than one half of 1 percent of the agents’ suggestions to secure the Southwest border mentioned the need for a wall…

Officials at Customs and Border Protection called the report inaccurate, saying it confused how agents’ feedback about security vulnerabilities is used to develop programs to counter threats.
