LOS ANGELES — A pocket version of the U.S. Constitution has become a best-seller on Amazon.com.

The Constitution emerged as a best-seller days after Muslim-American lawyer Khizr Khan, whose son was killed while serving in Iraq, flashed a pocket Constitution and offered to lend it to Republican presidential candidate Donald Trump during a speech at the Democratic National Convention.

"Donald Trump, you are asking Americans to trust you with our future," Khan said. "Let me ask you, have you ever read the United States Constitution? I will gladly lend you my copy."

U.S. Army Captain Humayun S. M. Khan, a Muslim, was was killed in 2004 when a suicide bomber attacked his infantry unit.

The 52-page pamphlet printed by the National Center for Constitutional Studies sells for $1 and was in the Top 10 best-selling books on Amazon on Saturday afternoon. The site produces an hourly list of its best sellers.

The version Khan used at the convention did not appear to be the same as the one that became popular on Amazon.

The moment, in which Khan accused Trump of having sacrificed nothing and no one, was immediately hailed as one of most powerful moments of the convention by people in the arena as well as on social media.
