During Sunday's edition of Fox News Sunday, host Chris Wallace reported from the Reagan Presidential Library in Simi Valley, California; where he and his panel reflected on the life of Former President George H.W. Bush. Liberal panelist Juan Williams used the opportunity to praise the late former President and contrast him favorably against President Trump; not an uncommon occurrence over the past 48 hours. Williams described the contrast between President Bush and President Trump as "optimism versus pessimism," contrasting the gentlemen's two slogans, "a kinder, gentler America versus American carnage." Williams also praised Bush's allegiance to Reagan's 11th Commandment of not speaking ill of a fellow Republican and contrasted that with President Trump, "who has a polarizing relationship with Democrats, clearly fractured, but also attacks other Republicans who don't agree or embrace him." Finally, Williams praised the 41st President for severing ties with the NRA in the wake of the Oklahoma City bombing and contrasted that with President Trump who suggested arming teachers in the wake of the Parkland school shooting and continued to business with the NRA. Wallace pushed back on Williams's criticism of President Trump, saying: "I'm not sure...that I would go along with the attack on President Trump because, frankly, not to say that he doesn't make mistakes and hasn't done some things wrong, but I think there's a culpability on all sides here."
