The tensions between Donald Trump and Senator John McCain escalated in 2015 when then candidate Trump insulted the Senator saying he didn't believe McCain was a war hero because he got captured during the Vietnam War.
On stage and in front of cameras at the Family Leadership Summit in Ames, Iowa, Trump infamously said:
"He's not a war hero. He's a war hero because he was captured. I like people that weren't captured."
Trump immediately denied making the statement. The animosity only grew from there, especially after Senator McCain joined Senators Lisa Murkowski and Susan Collins in their "no" votes on the repeal of the Affordable Care Act, a piece of legislation that had been a centerpiece of President Trump's campaign.
Recently, Senator McCain's daughter Meghan stated on the View:
"(Trump’s) comments are never going to be OK with me, especially at this moment in my life. I’m never going to forgive it. I’m never going to move on from it."
Because of these tensions, much was made of the fact that while Presidents Barack Obama and George W. Bush were asked to eulogize the late Senator at his funeral, the current President was asked to not even attend. However, Vice President Pence was in attendance as a 'representative from the Trump administration.'
But given the long history of discord between Senator McCain and the Trump administration, a certain facial expression from the late Senator's daughter grabbed people's attention.
