Trump has shown that there are still people who have never served, but still make ridiculous, insulting comments about veterans. Comments that should have been left behind long ago, in the dark days after Vietnam of blaming the warriors for the war. Trump’s asinine comments about Sen. John McCain’s service are an insult to everyone who has ever worn the uniform — and to all Americans.

I have had the honor of working with Sen. McCain on key veterans legislation, including the Clay Hunt Suicide Prevention for American Veterans Act, which was signed into law by President Obama earlier this year.

He is very capable of defending himself, but a public attack on one veteran’s service is an attack on us all. Trump’s stupidity is especially egregious given its timing — right after the murder of one sailor and four Marines last week in Chattanooga, Tenn.
