Koskinen is not a dim bulb. He is a dangerous partisan who should not be in his position.
Koskinen graduated Magna Cum Laude with a BA in physics from Duke University in 1961, where he was a Member of the Sigma Chi Fraternity and Phi Beta Kappa; graduated with an LLB, cum laude, (JD) from Yale University School of Law in 1964; and did post graduate work in Cambridge University, Cambridge, England from 1964 to 1965. He was later named a Significant Sig by the Sigma Chi Fraternity recognizing his professional contributions to society.
I grant you he has a good education and received honors.
I based that solely on him saying what he did in front of that committee, really dumb.
