Bush administration, according to the New York _Times_. They warned that a Trump presidency could threaten American security. “From a foreign policy perspective, Donald Trump is not qualified to be President and Commander-in-Chief,” the letter reads. “Indeed, we are convinced that he would be a dangerous President and would put at risk our country’s national security and well-being.” “He weakens U.S. moral authority as the leader of the free world,” the letter continues. The group said that they would not vote for Trump, but did not expressly say they would vote for his Democratic rival, Hillary Clinton. Signees include former Pennsylvania Gov. and the first Homeland Security Secretary Tom Ridge, former CIA and NSA director Michael Hayden, former Homeland Security secretary Michael Chertoff, former national intelligence director and Secretary of State John Negroponte, former deputy Secretary of State and William Howard Taft IV, the grandson of President William Howard Taft. Since receiving the Republican nomination in July, [Trump has garnered criticism from national security experts](http://time.com/4427551/donald-trump-hack-vladimir-putin/), including some who argue that he [should not receive classified briefings](http://time.com/4429507/hillary-clinton-donald-trump-james-clapper-intelligence-briefings/?iid=sr-link8). Many of the the aides who signed the letter were among those responsible for crafting the invasion of Iraq, according to the _Times_, which Trump has described as a “disaster.” ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4444125/trump-gop-security-experts/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4444125/trump-gop-security-experts/"},"headline":"50 GOP Security Experts Sign Letter Calling Donald Trump 'Dangerous'","datePublished":"2016-08-08T21:48:41.000Z","dateModified":"2026-08-19T07:45:45.099Z","description":"\"None of us will vote for Donald Trump\"","url":"https://time.com/4444125/trump-gop-security-experts/","keywords":["2016 Election","2016 Election","National Security","Donald Trump"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt7091f2c2fb0db12f/6988a197f887dc070de96ffd/donald-trump-002.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Daniel White","jobTitle":null,"url":"https://time.com/author/daniel-white/"}],"articleSection":"Politics","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt7091f2c2fb0db12f/6988a197f887dc070de96ffd/donald-trump-002.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Republican U.S. Presidential nominee Donald Trump attends campaign event at the KI Convention Center in Green Bay, Wisconsin","caption":"Republican U.S. Presidential nominee Donald Trump attends campaign event at the KI Convention Center in Green Bay, Wisconsin August 5, 2016.
