Khan, whose son died in the Iraq War, gained national recognition in 2016 when he slammed Donald Trump for his hateful rhetoric toward Muslims.
Despite his claims to respect veterans more than anyone, President Donald Trump has frequently made offensive statements about members of the armed forces and their families.
"It’s all about business with Donald Trump and his family. They have no idea what service and sacrifice is," the Gold Star dad said.
"The View" co-host told the president's son, "You and your family have hurt a lot of people," and asked, "Does all of this make you feel good?"
The Gold Star father also suggested someone should read the late Arizona senator's book to Trump.
Khan said "the same hate" that sparked the New Zealand shooting also prompted the Charleston and Pittsburgh shootings.
“We should embrace one another, we should move forward, we should not try to re-create the 1940s, 1930s,” the Gold Star father says.
"This office has not dignified him ― he has in fact undignified the office.”
The Gold Star parents weigh in on the president's controversial comments about consoling the families of fallen service members.
The father of a slain Iraq War veteran gave a stirring speech against Trump at last year's Democratic convention.
