President Donald Trump couldn't help himself on Tuesday while delivering his eulogy for late Sen. Lindsey Graham (R-SC) — throwing a quick swipe. Trump was giving his tribute at the Washington National Cathedral in Washington, D.C., when he went off script during the speech honoring the longtime lawmaker. "Virtually everyone — Republican or Democrat — liked Lindsey," Trump said. He was a tough cookie. He was a tough cookie, Darline, but he was beautiful," Trump added, directly commenting to Graham's sister, Darline, who was appointed to fill the vacancy after her brother's sudden death.
