Hillary Clinton took subtle jabs at President Trump during her Class Day speech at Yale, which she began by pulling out a Russian hat in an apparent reference to the ongoing investigation into Russian election meddling. The former secretary of State and 2016 Democratic presidential nominee noted the over-the-top hats students traditionally wear during Yale's Class Day and said she "brought a hat too." "A Russian hat," Clinton said on Sunday while showing the laughing crowd an Ushanka hat. "If you can't beat them, join them," she added.
