Senators wish Trump had stuck to honoring fallen Navy SEAL

The lawmakers said focusing on the success of the raid was wrong.

But Spicer and Trump went after Sen. John McCain, R-Arizona, after he told reporters on Feb. 9 that he would not describe the mission as a success given that a service member died.

Trump tweeted, in part, that McCain “should not be talking about the success or failure of a mission to the media. Only emboldens the enemy! He’s been losing so long he doesn’t know how to win anymore.”

Spicer said during that day’s briefing that the mission was “absolutely a success,” appearing to amend his previous comment.

“Look, the objective of the mission was not achieved. That doesn't make the sacrifices any less heroic and I imagine there would be some valuable information that was gathered,” he said.

"I think it's always appropriate when we recognize and thank the family of an American who is killed in combat. I would have preferred the president stick to that," Coons said.

While Owens’ widow Carryn attended the speech and was recognized with an extended standing ovation, his father Bill refused to see Trump at the dignified transfer and has called for an investigation into the circumstances surrounding his death, according to the Miami Herald, which interviewed him this past weekend.

"I think it is a cause of some pain for the family to sort of re-litigate the details of this particular raid, and I think what's important here is to thank and recognize Ryan Owen's widow, children and parents for the enormous sacrifice they've made for our country," Coons said.

U.S. Central Command, which oversees missions in the Middle East, confirmed that an investigation into Owens' death was underway as is routine after the passing of any deployed U.S. service member, but that there is no investigation into the raid itself.

"It kind of compounded the tragedy and the sentiment toward the widow who was there last night to know that there's internal family division. And some members of the family, the father, is really demanding that questions be answered," Kaine said. ABC’s Luis Martinez contributed to this report.
