Senator John McCain (R-AZ), the 2008 Republican nominee, is not down with Donald Trump's response to Khizr and Ghazala Khan, the Gold Star parents of an Army captain posthumously awarded the Bronze Star and Purple Heart in 2004. They appeared at the DNC and questioned whether Trump had ever sacrificed for America or read the Constitution. Trump responded that the visibly distraught mother was being kept silent because she was a Muslim woman, and that Khizr Khan had "no right" to go on TV and claim Trump hadn't read the Constitution.
