Congressional Democrats have found a useful ally in frustrating President Trump’s labor policy: the Labor Department’s inspector general. The Democrats have been able to get the official internal watchdog for the Labor Department to launch a blanket investigation of how the agency writes its rules and regulations.

Labor Department Inspector General Scott Dahl told key congressional Democrats about the blanket probe in a Jan. 25 letter. In essence, Dahl said he’d just add the Democrats’ latest request for an investigation in with the other ones they had previously asked for and create one big overarching probe for the whole department.
