President Donald Trump wants to merge the federal departments of Labor and Education in what would be the biggest bureaucratic shake-up in recent history, published reports said Wednesday.

Budget director Mick Mulvaney has been working on the proposed consolidation — which would need congressional approval — for more than a year, sources told Politico.

The combined agency would be called the Department of Education and the Workforce, Education Week reported.

This proposal would face an uphill political battle. Republicans have been seeking to eliminate the Department of Education for years without much success.

The last major cabinet-level agency shuffle happened nearly 40 years ago when the Department of Health, Education and Welfare (HEW) was broken up into the Department of Education and Department of Health and Human Services (HHS).
