Miller was introduced to Trump campaign officials by his cousin, Eli Miller, then a senior finance official in the campaign and now chief of staff at the Treasury Department, a Treasury spokeswoman said. On his LinkedIn page, Miller said he attended Cleveland State University from 2007 to 2011. A Cleveland State spokesman confirmed that Miller, who previously attended other schools, graduated in 2013. Miller described himself on his LinkedIn page as a Marine recruiter and said he worked for the presidential campaigns of Sen. Marco Rubio (R-Fla.) and Trump. But after The Post raised questions about his biography, Miller removed the dates of his education and the claim that he was a Marine recruiter. Miller has been charged by police in his home state of Ohio with multiple offenses. In 2007, he was charged with assault, disorderly conduct and resisting arrest after punching another male in the back of the head and running away from police, police records show. He pleaded no contest to two misdemeanor charges, and the case was later dismissed as part of a program for first offenders, court records show. In 2009, he was charged with underage drinking, a case that also was later dismissed under a first offenders’ program. The following year, he pleaded guilty to a disorderly conduct charge related to another altercation in Cleveland Heights, Ohio. That episode was related to a fight involving Miller shortly after leaving a hookah bar about 2 a.m. one morning.
