Historians valiantly tried, and mostly failed, to understand and interpret President Trump’s recent remarks about President Andrew Jackson. Among other comments, Trump seemed to assert that Jackson, who died in 1845, could have prevented the Civil War, which began in 1861, and that the causes of the bloodiest conflict in America's history have not been addressed or discussed. USSC research associate and assistant professor in presidential studies at the Miller Center, Dr Nicole Hemmer, is quoted in this Yahoo News article.
