The White House will announce plans Thursday to merge the Departments of Labor and Education into a single agency, according to a report by the Wall Street Journal.

The merger is part of a broader Trump administration effort to streamline the government but is likely to face resistance in Congress.

Merging the departments is an idea Republican lawmakers have pushed in the past.

It is unclear how the Trump administration would reorganize the agencies, which have significantly different roles. Currently, the Labor Department covers private sector workforce issues, and the Education Department mainly proves federal assistance to schools and enforces federal education laws.

Such a major restructuring would require Congressional approval, and it is unclear if lawmakers have any appetite for it. No legislation to that effect has been taken up in either chamber.
