Khizr Khan is getting involved in another presidential race.

Khan, along with his wife Ghazala Khan, the Gold Star parents of Humayun Khan, stepped into the national spotlight when he decried President Trump's proposed "Muslim ban" at the 2016 Democratic National Convention. Trump shot back with an insult for the Khans, and now, Khan is stepping in to try and stop him from being elected again.

In a Monday statement, Khan announced he's endorsing former Vice President Joe Biden for president because he "stands for" and "will fight for" the same America his son did. "Beating Donald Trump and the hatred he promotes is the top priority in this election," Khan continued, "but after Trump is gone, we need someone to unite us and help us heal." To Khan, Biden is the right choice to do that.

Khizr Khan endorses @JoeBiden: "Biden has always put the country above himself...President Trump, on the other hand, has consistently chosen self over country, seeking the aid of totalitarian governments to sway elections & undermine our rule of law to serve his self-interest." pic.twitter.com/MQiOBN40AT — Molly Nagle (@MollyNagle3) November 18, 2019

The Khans are Muslim immigrants from Pakistan, and Khizr Khan has been a U.S. citizen for at least 30 years. Their son was was an army captain killed in a 2004 while fighting in Iraq. Khan famously told Trump to "read the United States constitution" during his 2016 speech, pulling out a pocket Constitution and saying "I will gladly lend you my copy." Kathryn Krawczyk
