The pocket-sized version of the U.S. Constitution became a best-seller on Amazon.com Saturday afternoon. That is likely thanks to Khizr Khan, according to ABC News.
If you haven't heard Khan's name before, he is a Muslim-American lawyer whose son, U.S. Army Capt. Humayun Khan, was killed while serving in Iraq.
Khan slammed Republican presidential candidate Donald Trump during a speech at the Democratic National Convention. In that speech, Khan held up a pocket-sized Constitution and offered to loan it to Trump, insinuating his policies on banning Mulsim immigrants would violate it.
"If it was up to Donald Trump he (Khan's son) never would have been in America."
As Khan held up the Constitution, he addressed Trump, urging him to "look for the words liberty and equal protection of law."
By Saturday afternoon a 52-page pocket Constitution published by the National Center for Constitutional Studies was in the Top 10 best-selling books on Amazon.
Google Trends data also showed a sharp rise in the number of searches for "pocket Constitution" after the speech.
Trump has since responded to Khan.
On Sunday, House Speaker Paul Ryan, also reemphasized that banning a single religious group does not reflect the nation's fundamental values.
