He hadpreviously declined to endorse the three, who havedisapproved of Trump's criticism of the MuslimAmerican parents of an army captain killed in Iraq.

McCain is locked in a three-way race ahead of an Aug. 30 primary. The primary for Ryan's House seat is next week and Ayotte's primary is next month. All three have said they would support Trump as the presidential nominee.

However, all three chided Trump for engaging in a flap with Khizr and Ghazala Khan, the parents of U.S. army Capt. Humayun Khan, who wasawarded a Bronze Star and Purple Heart after his death in 2004.

From the podium of the Democratic National Convention, Khizr Khan criticized Trump's position on Muslims and asked whether Trump had read the Constitution.
