Morici made headlines in a July 2014 piece in The Hill, where he argued that the unemployment rate failed to take into account abuses in H-1B immigration visas and students who would be in the workforce but they were "duped" into enrolling in "useless programs" due to the prevalence of financial aid. Taking those circumstances into account, the real unemployment rate was 18%.[7] This figure was quoted by Donald Trump in a speech on June 16, 2015, where Trump announced he was running for president.
