Other claims were directed towards President Barack Obama. Trump blamed Obama for the 2014 Ferguson unrest with "President Obama has absolutely no control (or respect) over the African American community" as well as the 2015 Baltimore riots in "Our great African American President hasn't exactly had a positive impact on the thugs who are so happily and openly destroying Baltimore!" Trump also made unsourced claims stating that Obama "wasn't a very good student" who needed some sort of ambiguous help to get into college, suggested that Obama may not have attended courses, repeated on several occasions the conspiracy theory that Obama had Bill Ayers write his book for him, and stated, "Sadly, because president Obama has done such a poor job as president, you won't see another black president for generations!" Trump claimed that Russian President Vladimir Putin used "the N-word" to describe Obama, stating that this showed that Putin has no respect for Obama and that Trump himself would do a better job in such a position.
