"Have you even read the United States Constitution? I will gladly lend you my copy," Khizr Khan said during his speech last week at the Democratic National Convention.
That moment — when the father of a Muslim U.S. soldier killed in Iraq addressed Donald Trump directly — has been played many times over the past few days.

And it appears to have improved sales for the pocket-size Constitution.
But you don't even need to buy one. A quick Google search for "free constitution" leads you to a site where you can print one. Or, you can just go to the ACLU's website. It's running a promotion through the election that makes the pocket-size version free using a coupon code.
