Hillary Clinton became the first woman to ever accept a major party's nomination for President of the United States on Thursday night.
It was a big deal.
And, today, yet many people on the Internet are talking about someone they had never heard of prior to the Democratic National Convention, as opposed to this Presidential hopeful.
Did you catch the speech of Khizr Khan?
Khan's son, Humayun, was a captain in the U.S. Army.
When a vehicle packed with explosives approached his compound in Iraq in 2004, he told his men to take cover as he ran toward it.
It exploded and killed Khan on the spot, earning him a posthumous Bronze Star.
Fast forward 12 years later and Khizr Khan and his wife taking the stage in Philadelphia.
During a moving speech toward the end of the DNC, Khan paid tribute to his child; gave credit to Hillary Clinton; and offered a stark, brave repudiation of Donald Trump.
"We are honored to stand here as the parents of Capt. Humayun Khan, and as patriotic American Muslims with undivided loyalty to our country," Khizr Khan said to a standing ovation.
He spoke of his son's dreams of becoming a military attorney and how Clinton had referred to his son as "the best of America."
And then he went after Trump.
"If it was up to Donald Trump, [Humayun] never would have been in America," Khan said.
"Donald Trump consistently smears the character of Muslims. He disrespects other minorities, women, judges, even his own party leadership. He vows to build walls and ban us from this country."
"Donald Trum, you are asking Americans to trust you with our future. Let me ask you: Have you even read the U.S. Constitution? I will gladly lend you my copy."
With those words, he pulled a copy of the Constitution from his pocket.
"In this document, look for the words 'liberty' and 'equal protection of law,'" he said, once again to a raucous ovation.
Earlier this month, Trump promised congressional Republicans that he would defend "Article XII" of the Constitution.
There is no such Article.
"Have you ever been to Arlington Cemetery?" Khan said.
"Go look at the graves of the brave patriots who died defending America — you will see all faiths, genders, and ethnicities. You have sacrificed nothing. And no one."
Pretty powerful stuff.
