But Tom Blair, author of What would Ben Say? (Skyhorse Publishing; 2014), wants President Donald Trump to consider the words and thoughts of a variety of political and notable figures. The writer took a full-page ad in The Washington Post today headlined: "Mr. President," and explaining, "In anticipation of Presidents' Day consider the following words of counsel and caution." The ad listed 59 quotes, some focused on honesty and integrity, others on the importance of the presidency. Here are 10:
