The statement is so weird that I have tried to find an alternative meaning. One possibility was that he got a job teaching there. However, he never claims such a position. I am not sure when that could have happened. He became a bar member in 1969 and was elected the very next year to the New Castle County Council in 1970. Two years later he was elected to the United States Senate.

Another possibility is that he is claiming that he started his political career at the school, but again the campaign has said nothing and his own book does not mention the connection. Did he launch his campaign for the New Castle County Council at the university? I believe the university is about 45 minutes away in Dover from New Castle. He might be referencing his start for the Senate. The campaign however has gone days without explaining if there was a speech launching his campaign from the university (though that would raise some issues on the use of a state school). Absent such an explanation, the clear impression is that he attended a HCBU as a student.
