Trump constitutes a clear break with past presidencies. Gallons of ink have been spilled on Trump’s controversial use of social networks. Attention has been paid to his incautious statements on both domestic and foreign policy, which seem to be dictated at the spur of the moment rather than after an attentive consideration of the possible consequences for the United States and the world as a whole. Yet, less attention has been devoted to the impact the Trump administration had on constitutional and administrative law doctrines, and to the most recent trends in the U.S. government policymaking under Trump.
