Former Florida Gov. Jeb Bush criticized his party’s presidential nominee, Donald TrumpDonald John TrumpWhite House counsel called Trump 'King Kong' behind his back: report Trump stays out of Arizona's ugly and costly GOP fight Trump claims he instructed White House counsel to cooperate with Mueller MORE, on Sunday evening.

Bush, who dropped out of the Republican presidential race in February and has refused to endorse Trump, tweeted a link to a New York Times article about Trump’s remarks about Khizr and Ghazala Khan, the parents of a Muslim American solider killed in Iraq.

“This is so incredibly disrespectful of a family that endured the ultimate sacrifice for our country,” Bush tweeted. 

Trump sparked controversy late last week when he lashed out at Khizr Khan over his speech at the Democratic National Convention, which was critical of Trump. 

The billionaire doubted whether Khan prepared his remarks and questioned his wife’s silence on stage — which was the subject of the Times article Bush tweeted out with his comment. 

Trump in a statement late Saturday called Humayun Khan a "hero" but continued to criticize Khizr Khan, drawing a flood of criticism on Sunday. 

Many on social media pointed out the difference between Trump’s reaction to the Khans and President George W. Bush’s 2005 comments after facing harsh criticism from activist and Gold Star mother Cindy Sheehan. 

Sheehan's son Casey died in Iraq in 2004, and she camped on the edge of Bush’s ranch in Texas the next year, asking for a meeting with the president. At the time, Bush said, “I sympathize with Mrs. Sheehan. … She has every right in the world to say what she believes. This is America. She has a right to her position.”
