After facing the ire of the parents of a Muslim U.S. soldier killed in Iraq in 2004, Donald Trump was subject to mockery on Twitter with the hashtag #TrumpSacrifices trending on the microblogging site.

The hashtag gained prominence after the Republican U.S. presidential candidate claimed in an interview that he too has made a lot of "sacrifices" in response to Khizr Khan’s speech at the Democratic National Convention on Thursday. In his speech, Khan said that the real estate mogul had “sacrificed nothing and no one.” Khan, a U.S. citizen of Pakistani origin, in his address also told the story of how his son U.S. Army Captain Humayun Khan was killed by a car bomb in Iraq.

Trump attacked the speech questioning if Democratic U.S. presidential candidate Hillary Clinton’s speechwriters wrote Khan’s address and asked why Khan’s wife wasn’t allowed to speak at the convention. “She was standing there, she had nothing to say, she probably, maybe she wasn't allowed to have anything to say, you tell me,” Trump said.

In an interview with ABC News, Trump said, “I think I've made a lot of sacrifices. I work very, very hard.” He added that he had “created thousands and thousands of jobs, tens of thousands of jobs.”

In his May interview with CNN’s Wolf Blitzer, Trump said, “I’ve given up a tremendous amount to run for president. I gave up two more seasons of Celebrity Apprentice.”

A storm of jokes on #TrumpSacrifices found their way to Twitter with users mocking the 70-year-old New Yorker after his ABC interview.
