Trump's attempt to hit back in the ABC interview at Khan's criticisms quickly drew fire on Saturday.
Ohio Governor John Kasich, who was one of Trump's rivals in the GOP primaries, tweeted
Meanwhile, a tweet from Meghan McCain, the daughter of Arizona Sen. John McCain, made an apparent reference to Trump's earlier criticism of her father, who was tortured as a prisoner of war in Vietnam. Earlier this month Trump said McCain was not a "hero," adding "I like people who weren't captured."
Trump's office later released the full transcript of his comments about the Khans in the ABC News interview, in a statement called "Setting the record straight."
"As shown in the full transcript, Mr. Trump doesn't compare his sacrifices to anybody else's, and in fact praises Mr. Khan and wishes him well," the statement said.
According to the transcript, Trump told ABC News' George Stephanopoulos, " While I feel deeply for the loss of his son, Mr. Khan who has never met me, has no right to stand in front of millions of people and claim I have never read the Constitution, (which is false) and say many other inaccurate things."
Trump's comment about his sacrifices for his homeland, meanwhile, emphasized his job creation record.
"I think I've made a lot of sacrifices. I work very, very hard. I've created thousands and thousands of jobs, tens of thousands of jobs, built great structures. I've done, I've had tremendous success. I think I've done a lot," he said.
"I have raised millions of dollars for the vets. I'm helping the vets a lot," he added, noting that these efforts included being instrumental in having the Vietnam Memorial buitd in Manhattan.
