His father, Khizr Khan, gained national attention after speaking at the 2016 Democratic National Convention against Trump, railing against the then-candidate’s comments on Muslims immigrating to the U.S.

Khizr Khan has since become a prominent critic of Trump, accusing him of “disrespect” toward service members and tearing into his immigration rhetoric and policy.
