Trump initially said that he hadn't decided whether or not to endorse Ryan, in an echo of Ryan's initial hesitance to endorse Trump, although he ultimately said he would endorse the real estate mogul.
He also threw his support behind McCain, of Arizona, who he took to task for being captured and held as a POW during Vietnam.
"I hold in the highest esteem Senator John McCain for his service to our country in uniform and in public office and I fully support and endorse his reelection Very important. We'll work together," Trump said.
In addition to questioning McCain's military service, he also questioned his commitment to veterans.
